I just got the overheating issue as well, after about 30 minutes of shooting and the camera being on… in the sun, outside, at a park. The temperature outside was only about 60 degrees.
I was shooting 720p60.
Fry’s in Fremont, CA had T2i Kits in stock this weekend. It appears they are finally shipping. All of their stores showed stock, and you can order from them online, also showing stock. I just picked mine up yesterday in Fremont.
I am not sure I am loving the kit lens for video… very slow, and the focus ring is hard to control, since its so thin.
