CoSN has made the entire day of the International Symposium: Using Games and Simulation for Engaged Learning available online in streaming video:
There's an agenda posted on this page, you can generally judge where in the four chapters of video various sessions occur. There's some good stuff in there.
Mark Prensky kicks it off with a keynote based on his new book, "Don't bother me Mom - I'm learning". Lord (David) Putnam gives a good presentation in the afternoon session. Both of these have individual links to their videos from the agenda.
