I've just gone through various rumour posts elsewhere, and I think it's all guessing. Unlike the Sony leak, there's nothing at all to back any of it up.
60D might have a higher jump in functionality than previous updates in the series and bring it closer to D300 like level.
7D could be a value FF. I find it hard to believe they would recycle the 5D1 sensor. At this level I'm not sure making a brand new sensor would be economic unless it provided other manufacturing benefits as opposed to technical benefits. So, could they cripple the whole 5D2 design enough to differentiate it? Compare 1000D to 450D for example. A bit less features for a bit less cash, where the cut down features are enough for people to go, should I pay more for the full monty?
As a wild card comparison, also consider the A900 and 5D2 launch. Sony goes "Hey everybody, we have the highest pixel count FF at 24MP. Check this out!" Everyone goes wow, as well as other comments I wont repeat
A few days later Canon goes "Ok, we don't exactly have the same MP but close enough, but we have more toys and, by the way, we're Canon". Could we draw a parallel with that? I know this is speculation based on what are still rumours, but Sony are thinking "A850: even cheaper FF. No one else has one. The market is ours.". Canon goes "*cough* 7D. We can do it too.
