No Wii list? I'll help haha. No specific order:

1. Fatal Frame IV- survival horror

2. de Blob- platformer

3. Tales of Symphonia: Dawn of the New World

4. Fragile

5. Little King's Story

6. Deadly Creatures

7. Wii Music

As soon as E3 comes around will be able to add a lot more considering I had to leave a few off due to not knowing release dates. Sure we'll be able to add Kid Icarus and Animal Crossing to that list eventually. Man give me FF4, Fragile, ToS2, Wii Music, and Deadly Creatures from that and I'm happy. And still got Little Kings Story and De Blob left over haha. Not bad 7 exclusives coming out later this year eh.

Even if Sony does announce new games and flaunt some "hidden" ones (GoW 3) most of those new ones wont be avaliable for a while (Uncharted 2!) so M$ probably does win... if you are an RPG fan!
Having said that, you forgot Motorstorm and Halo Wars will almost certainly not be out this year (nor will Heavy Rain)

I believe the 360's lineup is more impressive than the PS3's. Personally, I am most excited about GOW 2 and Left 4 Dead.

You for got:

Motorstorm 2
Disgaea 3
Valkyria Chronicles

360 has the best lineup of the remainder of 2008, mostly because of the advantage the PC/360 titles like L4D and Red Alert 3 give.

Wii, unfortunately, still has a severe lack of great games coming out soon.

Ofcourse none of the consoles can match the superiority of PC's lineup, which is amazing.

Post means after.

You can add Lips to Msoft's exclusives list, as it has been just confirmed by a couple of sites to be present at the show.

All in all I like M$'s line up a bit more, mostly because of Left4Dead. A good showing of LBP or some God of War 3 footage might swing the scales towards the PS3, though.

what about Final Fantasy XIII, God of War III,  inFamous?

plus you forgot about the wii's list
