I watched this earlier today, and just.... Wow. This just looks like boat loads of fun. It seems like there's gonna be so many different ways to approach this game that no two people's experience will be the same. I mean, just look at all the different ways Snake methodically dealt with the PMC soldiers. Throw in the likely possibility that a number of gameplay mechanics haven't even been revealed yet, and this looks like a true next-gen experience; it's definitely a big step up from past incarnations. I don't think I could be more excited for this game than I am now.
My Top 5:
Shadow of the Colossus, Metal Gear Solid 3, Shenmue, Skies of Arcadia, Chrono Trigger
My 2 nex-gen systems: PS3 
and Wii 
Prediction Aug '08: We see the PSP2 released fall '09. Graphically, it's basically the same as the current system. UMD drive ditched and replaced by 4-8gb on board flash memory. Other upgrades: 2nd analog nub, touchscreen, blutooth, motion sensor. Design: Flip-style or slider. Size: Think Iphone. Cost: $199. Will be profitable on day 1.
