"The most annoying thing about the 60D in terms of handling is the fact that the camera will overheat after prolonged periods of video-mode use. The live view mode, which is necessary for recording video, causes the camera's internal components to get to hot and, in turn, the 60D will automatically shut down when this occurs. Now, we only had this happen to us once during our testing (and it was after 30 - 40 minutes of straight use in video mode), but if you're doing a long day of shooting it is most likely going to occur. And, if it does, you must let the camera sit for a few minutes before you can use its video mode again."
Incorrect? As in, is it possible for a 60D to overheat? Sure. But it's much better than it's predecessors, and under "normal" conditions, which I was attempting to test in, it can shoot for several hours with no problems.
Unfortunately, DCI doesn't give any information about the circumstances they where testing under, but they did say it only gave them a problem once. Beyond that, it's a pretty resoundingly positive review and the #1 rated camera on their site right now. If you're considering shooting with one, I doubt you'll be very disappointed. There are a lot of people out there getting good results with it.
