1 unannounced PS3 game from IREM

1 unannounced PS3 game from Konami

9 unannounced PS3 games + 3 unannounced PSP games from Sony Computer Entertainment

First of all, there's a good amount of playable games. In fact, all identified games will be playable. That's a good thing.
Secondly, there's that IREM game which I can't remember if it's that other R-Type game, not necessarily a pure shooter, or an adventure game. Well, it's not really the same IREM anymore, but hope doesn't hurt, right? Maybe it's that Hototogisu tactical card game.
Thirdly, and probably the most important part of all, Sony will present 9 first party games for the PS3, and 3 for the PSP, all kept secret for the moment.
It's only after most of this batch of new games will have been released that Sony will know how to proceed with the PS3's price.
