Wow, good question. I’m guessing it’s High Profile, but not 422 (I think it’s 420) at level 4 or higher. It uses a variable bit rate. We just shot some footage last night on the 7D (I truly wish I had one of these myself, but I love playing with the footage anyway). It’s got a bit rate of around 50mbps (about 2x normal AVCHD at the high setting).
Of course, this is a guess as I don’t generally deal too much with the hard tech side of things, but it was such a unique question, I had to look it up.
