If you head over to
You will see four little windows
One for MGS rising, one for MGS peace walker, one for castlevania and one for Metal Gear arcade
Now first of all there's apparently going to be a MGS arcade game which probably will be similar to the multiplayer in MGS4
The next notable thing is if you look in the window for MGS rising you will see the PS3 logo indicating that MGS rising is not a 360 exclusive.
Now last but not least if you go to the castlevania window and clcik it you will be able to watch a trailer for the new castlevania game. The trailer reveals a subtitle for the game which is Lords of shadow, also it will be released in 2010 and apparently kojima productions is involved in the game.
