Searching for "Canon" on Google News doesn't give any results for a credible news agency picking the story up.

Did the official press release happen yet (still don't see it updated on the USA canon newsroom)? If not, still holding out for a possible lens announcement too!

I don't think so.  www.canon.com/news/2011/index.html still only shows the "50 million EOS" news release that states the name of 1D X but no specs.

Hmmmm......

The 7D shoots 18 MP RAW files at 8 fps with dual Digic 4. If the Digic 5 is indeed 17 times faster and the 1D X has dual Digic 5 plus Digic 4 for metering, why can't it handle RAW at 14 fps? That's not even twice as fast at moving data as the 7D, unless it turns out to be foveon type sensor or something.

It's a good question.  To get the 14 fps the press release stated the mirror would stay up but still the sensor is being exposed at 14 fps and converting to jpg is additional processing after the RAW exposure and ADC so why not allow RAW at 14 fps with the mirror up?  The answer then could be that data throughput to memory is still the bottleneck?

Also, the press release didn't mention of how many frames at 12 fps the camera can capture before the buffer is full.

For networking, it looks like a LAN port with the option of wireless (with on-board bluetooth) and GPS adapters.

I like the idea of colour-based focus tracking with iTR (Intelligent Tracking and Recognition).

I like this translation  "Operation of the shutter unit cleared the test for 40 million times." now thats what i call durable :D

Pffttt...  That's only 33 days at 14fps, you call that durable?

If anyone complaining about the 'wired' ethernet wants to transmit 1 RAW file every 5 seconds over 54Mbps wireless, be my guest. I'll stick with the gigabit.

Considering studios already shoot tethered via USB, maybe they just decided gigabit was more ubiquitous and easier to implement than USB 3.

True.  And every computer (mostly) has ethernet (although perhaps not gigabit) while USB 3.0 has been slow to be adopted.

While most people are trying to go wireless, Canon gives us a wired network system?  Seems odd...  can you imagine a bunch of 100+ yard ethernet cables cluttering the sidelines of a football field?  Not to mention that I think it would be rather cumbersome to manipulate a camera with a giant cat6 cable sticking out the side.

Yeah that couldn't work at the sidelines... the photographers move around a fair bit.  Perhaps their intent is that a Gigabit ethernet connection gives super fast image download in the press center rather than actually shooting with the cable attached?

I think you guys all forget that pretty much all pro STUDIO work usually means the camera is wired to a laptop or computer. Just because there is a new feature doesn't mean it's geared to every single use of a camera.

Ethernet technology in a wireless society just to serve studio applications still makes no sense in the broader picture. Including an ethernet port on a camera requires a sizable commitment in both on board technology and port space...I just can't see stepping backwards for this function.... :)

That's a good point also.  Adding an extra port (a fairly large one at that) and a comm protocol is strange.  As for speed, USB 3.0 is 5 times faster than Gigabit Ethernet... do I have that right?

Good point.  The "possible press release" made a reference to sporting arenas equipped with wired LAN so naturally that's where the mind goes.

It appears it could be true, if you take a look at the following press release on the Canon site it makes mention of the EOS-1D X with the same release date:

http://www.canon.com/news/2011/oct18e.html

Yeah, that does help with this a lot, but some of the specs are still strange, so someone could have made up some specs to throw in. At least we know the name of it :) Just have to see if the specs are right.

Good call!  Maybe someone read the Canon release about the name and plugged in the rumoured specs!!!

...and why does the 4th paragraph refer to a Digic 4 processor .... I thought this was Digic 5

The reference to DIGIC4 is just for the AE (and maybe the AF?) system.   The camera operating system and image processing is done by dual DIGIC 5+.

2.5 hours to go!

what time is it suppose to start? noon SGT?

If it's going to start at 0400 UTC/GMT (ie in another 2:15) as has apparently been tradition, that makes it 1200 Singapore time, 1430 Aussie time (the parts of Aus that matter anyway), 1300 Tokyo Time, 0600 Western Europe (Berlin time), midnight New York, 9pm monday in LA, etc.

Yes, i'm so bored waiting for this that i've been messing around on timeanddate.com.

LOL I was just on there as well.

BTW, for those interested in when this announcement will actually be, I could not find any references online to a time but in the past almost all of Canon's major DSLR announcements have come at 04:00 GMT.  The only exception was the 1D4 which came at 08:30 GMT - at least according to DPReview.

Sounds like the right time to me. It will be 0:00 EST so that would be all 7 continents on 10/18/11.

That could be part of their consideration... by 0:00 EST at least part of North America will be on to the 18th.  They could wait 3 more hours, 4pm Japan time, so that all of the Continental US is on the 18th but then they wouldn't make the morning papers in New York.  Maybe they just like 1pm Japan time when they get back from lunch.

In a perfect world you can have 12 stops using just 12 electrons and cell phones would have great DR.

No.  A stop is defined as doubling of the signal.  So let's say your noise floor was 1 electron... then you'd have less than 4 stops by the time you got to 12 electrons.

I do not understand why people always associate dynamic range with pixel size. The Nikon D7000 has wider dynamic range than the Canon 5D despite the smaller pixel size.

Uuuh, where did you see that people associate DR with pixel size? As I understand it, DR is the amount of different stops (from lowest to highest) the camera can record on one shot.

Dynamic Range is the ratio of the largest to smallest signal that can be recorded.  The largest signal is the maximum number of electrons that the photosite can hold (full well capacity) and that scales with the size (area) of the photosite.  Therefore, DR does go up with the size of the photosite for a given noise level.

Important to note that the size of the photosite (the light sensitive part) is not the full size of the pixel... the amount of space it takes up is called the "fill factor" and has typically been less than 50% but that may have been something that Sony has improved upon.

The Sony sensor in the D7000 was a great improvement because the the full well capacity is almost as high as the 5D (the 5D2 is larger).  The read-noise at ISO 100 was also reduced in the Sony sensor.  The net result is that the D7000 has a very large DR.
