He spends a lot of time at the start saying "I'm recording my own commentary. This is really cool." He talks about working with the animators in Hong Kong, scenes that were deleted, how he wanted all 4 actors that played the turtles to be in the same room during the recording so that they can bounce off each other and his reaction to Mako's death. He heard about it on his visit to Comic con just after he announced Mako would be in this film.

He mentions all the voice actors, but not Ziyi Zhang and Laurence Fishburne.

A nice track, but don't expect anything Turtle-tastic.
