Just looked over the details, seems good... but then I love my 60D. haha
No in all serious things and all its does look good..... but and its a big one, I may buy one eventually but at present along with many others it might not offer enough to make people want to buy as even in looks and button placement, its neary identical to a 60D even down to the top screen lcd. ( not a bad thing at all, 60D feels great)
Although interesting to see its smaller than the 60D, quite suprised by that, though it would be slightly larger as in 7D size.
But at £500 more, I wait with baited breath to see how good the new sensor is as it is bigger than the 60/7D sensor (albiet only 0.2mm and 0.1mm respectively) so should be good to see the new sensor put through its paces.

Can't wait though as hopefully it will be awesome ... then I may have to have a rethink. haha

the video does look good, seems a neat camera, and the 60D discontinued... hmm, might be time to buy another! haha
Or wait for this to come down slightly
