I just played the second demo on the PSN store and I am just absolutely in love with the way the story is told. The art and music and presentation of the story come together as such a hauntingly beautiful package that I will absolutely be buying this game some time soon. I would buy it today, but I'm waiting for all the reviews to come in for all the big Fall titles before I start spending my limited funds.
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.
