there is no commentary on the time lapse... frankly, even if there were, I wouldn't have much to say. It plays at about twice normal speed. When the videos are up, feel free to ask questions if you have any in the VIP forum.
Even so, most of the stuff the time lapse covers is stuff that has been talked about already in previous videos, such as the head modeling tutorial and the rigging tutorial. When it gets to the texturing, they'll be realtime videos for simplyphotoshop and the animation of the character will be realtime for simplymaya.
I know one of the main helps I always remember have been time-lapse examples that artists sometimes display and I hope this one is helpful to you folks as well.
