I think its a great camera and will be an UPGRADE from the 7d in many ways that many people find useful.
VIDEO for sure
I think the AF will be just as good, and if it isnt, it wont be measurable without microsecond tools. LOL
wifi will be very cool.
As for the flip out screen, you guys know the screen can face out and stay IN the back of the camera just like the 7d and every other older camera's fixed screen. it can not break off in that orientation.
I owned a 60d for a year. loved it. sold it and got a 7d and sometimes wish I still had the 60d instead. I miss the flip screen for low angle shots that I dont want to lay on the ground and the 60d had slightly better high ISO properties.
as for the button layout, its really intuitive on the 60d and this layout is very similar to the 6d Im guessing. The directional pad is nice as it can be reached in vertical or landscape orientation. thats a win because its awful to reach the joystick on the 7d in portrait orientation.
This camera is a win in my book. I will think hard about getting one while waiting to see what the 7d2 may bring.
