So, it looks like Think Services put up a version of my slides that was sent for speech approval rather than the version that I actually showed at GDC. Boo-urns. Hopefully they'll update it with my real slides soon.
In the meantime, you can get the slides that I showed here - as well as a bonus slide that was approved, but was cut for time:
Dirty Deeds Done Dirty Cheap: Design Lessons Learned from ROCK BAND
I'm sure once all of this dies down I'll write up a nice postmortem of the GDC process, it's been hair-pullingly interesting and intriguing.
