What I think is that the games in 09 shows a big impact in the Playstation 3 because there's a lot of new exclusvies for the system (KILLZONE 2, God of War III, and other PS3 games I cant think of). Lots of Halo titles for the Xbox 360 and new maps and Alan Wake a long waited title for the 360 hopefully coming out this year or next year.
The Wii line-up is still unknown. I dont think any Zelda games are going to be shiped out this year and still nothing about any Mario titles are being announed in 09.
For all Final Fantesy fan out there FF 13 won't be coming out in 09 but coming out in 2010.
But in bigger new Guitar Hero Legends of Rock. Rocked out about 1 billion dollars in games and DLC (Downloadable Content) out the Wii, Xbox 360, PS3, and PC.
