The 5DII does 60fps using it's entire sensor at 720p. So Canon knows how the bind pixel to get higher fps.
Since when?????

It doesnt? My bad :) ~ I dont have a 5DII. But it does 30fps @ 1080p. My point was that when lowering the resolution by binding pixel together, the 5DII can read its sensor faster.
Damn, I thought I missed a firmware upgrade or something. Your point is valid.

30+ Mpx means at least 35MB files x 10 = 350MB.

My SanDisk 128GB PRO UDMA7 memory card is capable of writing up to 110MBps,
if you have two cards in parallel you can achieve up to 220MBps.

You can of course have a faster buffer, but this buffer would have to be pretty large.

For me the most important factor is what the camera is capable of delivering to the
memory card over time, not only to the buffer.

My SSD harddisk, which currently is the fastest in the world, the OCZ 240GB IOPS SSD,
can write up to 500MBps. Maybe if bringing a computer out in the field you could connect
your 1Ds Mk4 via USB 3.0 and be able to write 10fps @ 30Mpx. But I will not do it !

I just don't get it why Canon cannot jump of the megapixel wagon and leave their
camera at max 25Mpx. Who on earth needs more?

More important is better ISO performance, CONSIDERABLY BETTER ISO PERFORMANCE !!!,
and SPEED !! on a full frame pro body!

All I can say is thank heavens, and please get a move on! 

Any idea if the new 24-70 be intro'd with it?

CFast cards are much faster than SD or CF cards. Problem is they have not been used in camera yet. But chances are its mainly because they were not needed yet.

Also, It doesnt mean that 30mp and 10fps has to happen at the same time. Sacrifice resolution for speed could be a good compromise that already exist in the 1D vs 1Ds line.

Sadly it can't. The 5DII simply drops pixels which messes with the bayer pattern, introducing aliasing artifacts.

With the 7D around, people who need a sport camera have a great camera with capable auto-focus. Maybe Canon know the next 7DII will have the 45 point AF or something even better. For those who need range, the 1.6x is also a nice thing. So why keep the 1D around?...

That could also I spose have the benefit of making it easier to differentiate product lines with AF...

Pro Grade - 1Ds & 7D

Current 7D Standard  - 5D and xxD

Current Basic - xxxD and xxxxD

The same could be true with FPS aswell, a 1Ds Mk4 with 10 FPS vs say a 5D mk3 with 5 FPS provides much more of a differentiation than they currently have.
