Comparing the 2 cameras there seems to be only little differences between them for the video side.
The 5DMK2 does have a bigger sensor, but I don't think that will make much difference in these videos.
This is a big misconception: the difference in sensor size will make a HUGE difference to the look you'll get. 5DII is a hell of a camera, although "hell" could be taken quite literal here as it is very difficult to keep things in focus with it. I am an experienced operator, but shooting a scene with actors that move only a few centimeters out of their ballpark is already giving you a headache at the end of the day. But when all goes well (and you know how to keep the entire processing of the files under control) the results can be stunning.
Personally I would not consider the 60D, but instead the Panasonic GH2. Test that one against the 5DII and see which one suits your needs best.
