PS3 and GT nut in the house. I'll gladly spend a ten dollar premium on GT5p compared to GT4p considering it is a next-gen game with online. I personally don't judge the worth of a game based on the content that's in it (I know, I sound crazy, but bear with me). I judge worth based on how much fun I'm gonna have with whatever content is in fact included. GT5p could have every car and track from all over the world ever, but if it played like Ridge Racer 1 and cost $40, I wouldn't touch it with a ten foot pole. I have a pretty good sense that I'm gonna spend at least 5 and as much as 15 hours with the license tests and arcade/simulation mode. Throw in another 25 hours online, and I will have spent RPG-like time with GT5p all at a price $20 less than a brand new next-gen role player. So, for me, and probably 1/2 million others, this will be totally worth it. That also means that Sony is totally sane and justified in their pricing.
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.
