I also feel as though Sony has had far too many first parties without enough quality. A lot of big Sony fans love to point out how Sony is the largest First Party publisher in the world, but the problem is that they have such a low rate of quality compared to MS and Nintendo.
That's not to say they don't make a lot of good games, it's just that the ratio of good games to bad games is not nearly as good as the other two.
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.
