Ok then, since you want to parse and nitpick, let me clarify, the 60D is not intended to be used by stills professionals. Sorry I left out the word "stills". But again, it's just not. I also find it hard to believe it's intended for video professionals. I would still say it is not. Doesn't mean they can't use it, or even that it doesn't work well for you...I'm happy to see that it does. But don't sit there and tell me the 60D is intended for video professionals. It's intended to be what it is, an overgrown Rebel designed to fill a small gap in a camera lineup three years ago.
I apologize for looking at this from my still capture perspective, and you all are making interesting points about the lack of a 60D overheating when used for long periods of continuous video. It appears I do stand corrected on that. However, my perspective is different from yours. I wonder how many gigantic red and purple spots due to blown pixels, would show up on that sensor, say if you did longer exposure night photography (as I am known to do) at ISO above the minimum? Say a 2 or 3 minute exposure at ISO 640? If you claim there are none, then that would be hard to back up...because you could simply provide an image that was shot by a body that hadn't seen much video usage (or otherwise clone them out) and I would just have to take your word for it.
Sure, I mean, if all you care about is video, or if your work even buys the bodies for you, then by all means, go nuts. Use and abuse it to the max. I've rarely seen anyone who doesn't own their equipment, not put themselves before the equipment they use. I buy my own equipment, and I don't do video at this time...other than non-pro work with a consumer video camera (for which I consider myself more than a decent videographer. I may have been doing it before some of you were even born, you know, back in 1990).
Just keep in mind, the main reason video professionals use DSLR's (especially the smaller crop bodies) is because it helps their bottom line, and allows for the purchase and usage of many more cameras...not because they generate high quality video. I'm not judging, just stating fact.
