Well would that make sense ? I mean I think the 5DmkII is still selling pretty well, and specially a lot of people (including me) were waiting for the 5DmkIII annoucement to go FF, have been disappointed by the price of it, or not rich enough to afford it, and thus bought a 5DmkII that has been for 4 or 5 years described as the best camera ever, or something like this ... if they do some kind of update of the 5DmkII they'd disappoint most of the people who went straight to the mkII when finding out they couldn't afford the mkIII ! And I don't mention the fact that A LOT of photographers are really really fine with 9 AF points ...
Just because something is selling great does not mean the company should stop making a new product. For example, just because apple sell their iPad2 in millions now didn't stop them from making a new iPad.
I think as one of the poster said, price point of somwhere 2500-2700 is missing. That would basically put this so called new FF camera right between 7D and 5DMK3 from price point.
I was thinking the same thing maybe FF body with some of the 7D AF (19 points) and lower FPS (maybe around 4.5), Digic V, stick with 3" screen, single CF card slot, etc. and price it at around 2600 +/-100 USD. I think this will keep a lot of people happy.
Canon might throw a curveball just like when they announced 7D when everyone was expecting the 7D to be the 50D replacement...but bit later announced 60D. Who knows...maybe move the xD line to the FF and whatever 7D's replacement back into the xxD line.
I am sure Canon is watching how the sales of 5D3 is for next few months. Just because something is in development does not mean they are going to market it. If this is lower priced FF, you know it can't be better than 5D3 just 7-8 months later (if fall of 2012 is true).
In the mean time, I better get snap happy and create more work.
