Canon is caught in a trap of its own making, as much as Nikon's. 

Agree 100% with your analysis.
It’s interesting what Canon will decide about the 1.3x format.

No matter how many megapixels a 1.3x camera has, it is bound to remain a specialized sports camera - good if you have a big white lens bolted on it, not so good otherwise.
At the same time, if Nikon’s D4 has 20+ megapixels, it will be an excellent general purpose pro camera, not just a sports camera.
If Canon continues with the 1.3x format, they will be competing with a specialized pro camera vs a general purpose pro camera.
The specialized camera seems to be at a disadvantage here.

So, it does make sense for Canon to move the 1D series to FF.
The thing is, this already made sense back in 2007 and yet Canon did not do it when the 1DIII was released.

But if Canon does decide to move the 1D series to FF, some very interesting opportunities will open up for the 5DIII and the 7DII.

This new rumor makes a lot of sense.

The 1D/1Ds pairing is not sustainable anymore.

This pairing was working fine for low-res/hi-res cameras but will not work for hi-res/even-higher-res cameras.

To compete with the upcoming Nikon D4, the 1DV will have to have a FF sensor (likely 20-24mp) and sell for no more $5500.

With that, Canon will have a very hard time charging much more for the 1DsV - if it's basically the same camera as the 1DV but with more megapixels (50mp?) and slower fps.

To charge more for the 1DsV, they need to better tailor it for its intended market, which is the hi-res studio market served currently by MF.

Canon will most likely keep the EF mount and the FF senor (24x36mm) but the body format will change to better fit its intended use.

Maybe Canon will make it an interchangeable-sensor camera, so that it is more future proof.
Also, they may decide to make multiple variations of the 50mp sensor (say a B&W variation, a variation with 6-color filter, etc.), so a modular design makes a lot of sense.

Yup. Finally some meaningful info.
I guess all those 'sources' that 'predicted' a 1Ds4 at Photokina can safely be written off  ;D  ;D

So, which cameras will Canon refresh next and in what order.

The 5D classic was updated in its third year and the XXD series has been on an year and a half refresh cycle.
Following the same schedule, the 7D should see a refresh next spring and the 5DII next autumn.

Let the new rumors begin :).

Canon has been very tight lipped this past year, though.

The 1Ds4 for Photokina is not happening.

Canon is preparing to introduce a new generation of sensors and the Digic4 is very old now, so a 1Ds4 is not happening at this time.

They will jump straight to the 1Ds5 with ~50mp and Digic5 sometime next year.
My crystal ball tells me, though, that the 7DII will be the first one with the new sensor tech.

Btw, check out the last paragraph of IR's report of Canon Expo 2010:

While it wasn't included in any announced product, a number of the exhibits were based on a 50-megapixel full-frame CMOS sensor chip. Given how often this chip was mentioned, we'd guess that a 50-megapixel full-frame digital SLR can be expected to appear in the not-too-distant future.

So, a FF back-lit CMOS sensor ? ? ?

ROFL  ;D ;D ;D.

This so called "source" has no clue about what's going on in the semiconductor industry today.

Resizing a 18MP image to 10 MP using a decent algorithm is not very much different to using a 10MP sensor with larger pixels in terms of signal processing.

In theory you are right but in practice you are wrong.

What you are saying is true only if the two sensors collect the same amount of light. 

Consider this, though - the top surface of a sensor has an 'active' area (which collects light) and a wiring area (basically a dead area in terms of light collection).

More pixels on a sensor requires more wires.
If two sensors use the same wire size, more wires = larger dead area (and hence smaller active area).

So, an 18mp sensor will actually collect *less* light than a 10mp sensor - if both sensors use the same size wires and everythng else is the same.

FYI, Canon has not shrunk the wire size of their sensors since they started making sensors in 2003 (?).

Finally  :) :) :)
This looks like the real thing.
I guess the rumors about the swivel screen were true after all.

Naah. Next 1-series will be announced early next year - Digic V, reworked body, etc..

At Photokina we'll have a PowerShot with a slightly larger sensor (10mm diagonal).
Also the 60D and maybe the 5D3.

The revolutionary part in the PowerShot will be the zoom range - Canon just patented a technology for a compact lens with a large zoom factor.

Canon General / Re: Canon Looking at a Medium Format Company?

Completely agree.

Also, in the next couple of years both Nikon and Canon will have 18-24mp pro cameras at the $5K price point.

This will seriously challenge the $8K price point for FF cameras - regardless of megapixels.
Only larger than FF sensors will be able to easily command $8K+ prices.

So, it will not be so surprising if Canon buys Pentax as a vehicle to sell expensive MF sensors.
