It's probably because I haven't really played R&C before, but I have a bad feeling it's not gonna pull in the big numbers like the reviews scores or SSJ might indicate. I don't think the game hits the hardcore (mature) fanbase of the PS3 and therefore the game will sell like Heavenly Sword.
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.
