At Dan Loosen's request, I will have my PS3 there, and I will have my 32-inch LCD HDTV to hook it up to. Also, I will be bringing the original Fantasy Star Soldier US pressed beta CD for the TG16 Museum.
If we can get wireless Internet working, I have the Warhawk beta for people to try out as well

I was going to bring my TurboExpress, but I'm already bringing my laptop, DS/games, and my PSP and games, so I think I'm leaving my Express at home.
For PS3, I will have 4 controllers, and to play we'll have:
MLB 07: The Show
Resistance: Fall of Man
Motorstorm
NBA Street Homecourt
NBA 2k7
Ridge Racer 7
Virtua Fighter 5 (with 2 Hori Fighting Sticks for the PS3)
Tekken 5: Dark Resurrection
Calling All Cars (4-player split-screen)
