I did a little digging and found two additional resources from the CoSN K12 International Symposium. The first is the video that was shown to open the day by the George Lucas Education Foundation:
Simulation Nation (video, 11 mins)
The second is the Edutopia Article from Marc Prensky, Simulation Nation. Marc was the Keynote Speaker at this event, and this article is featured in the current edition of Edutopia. This is an excellent article that Marc drew heavily from for his keynote presentation.
