I've never heard of a game having such a nebulous release date all of a sudden get an official release date a month before release. Don't get me wrong, it would be awesome, but come on. Does this sound like Sony's M.O. at all??? As soon as Sony has a vague idea of a release date, they trumpet it like no other even if the game isn't coming out for years.
And to anyone who believes GT PSP wouldn't get completely overshadowed by GT5, think again. Sony has said half of PS3 owners own a PSP. Then consider if you owned both a PS3 and PSP, would you spend $60 on GT5 and then $40-50 for GT Mobile? It just makes too little sense.
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.
