Same.  "Just wait til E3!"  Except that Sony could also very well pull out a lot of surprise announcements.  As of this very moment, the PS3 has the best lineup by a mile.  Of course, it's all subject to opinion.

And I believe Call of Duty 4 was officially announced at last year's E3, and was released the same year in November.

Is starcraft 2 a console?
Anyways, if you go by anticipation and what's on paper, It's PS3>360>Wii
However, we don't know all the details and no one knows what sleeper hits or flops might await us. Games like Infamous, Too human, or deblob might turn out to be great AAA titles. So we won't know this answer until 2008 ends, but for now, it's easily the PS3.

1. You left Resistance 2 off of your list.  That's a big game.  And J&D: The Lost Frontier hasn't even been announced.  All we have so far is a trademarked title. :|  For the most up to date exclusives list see this thread.

2. It's a given that GT5 won't make it out until 2009 (as well as a few other titles on the list that are practically vaporware, like Eight Days, but nobody realy cares about those), but when you include high profile 3rd party exclusives like MGS4 and Tekken 6, it makes up for it.

3. Yeah, it's a given that Nintendo generally holds their cards until the last minute (MKWii pretty much came out of nowhere), but my initial comment was geared more towards MS.  They usually announce there games years before release (Banjo 3, Halo 3, and Mass Effect being the most notable offenders) just like Sony, so the chances of them suddenly having a bunch of big games announced for this year at E3 is slim to none. 

In the end, the Wii could best the ps3's line-up, given a few major games are announced throughout the year like Star Fox or Kid Icarus, but the 360 has no real chance to come out with more games than have already been announced.  And it also could have it's share of delays, like Banjo 3, of which we've seen only one CGI trailer back in 2006.

As of now PS3 has the most exclusive that appeals to me this year

at the moment, ps3 easy.

however, it's march. there are games still be be announced by the big 3. also, it's hard to tell which games out of the lot will actually make an 08 release.

I think the Wii has the best games in 2008 simply because so far they have their three big guns already, or almost out, world wide with the possibilities of many more for the second half of 08.

I also have little faith in third party developers releasing their games in 2008 for PS3, or it would easily win. The chance of so many delays kills my confidence in it.

Xbox 360 has heaps of games, which i am going to fork out heaps of money for.
(Starting with GTA4 for me)

PS3 has some much anticipated AAA games that i want (MGS4 is my first game for PS3 this year)

Wii has some good titles, i own a Wii, but sadly i don't play it much. (I might look at Mario Kart Wii though)

All three consoles have so many great games coming out this year that it comes down to personal preferences. I'm personally looking forward to the Wii the most, but that's mostly because it's the only console I own. The PS3 slightly edges over the 360 in my books as, but not by a lot.

I would consider it fair to say the Wii is going to get more new games announced for the rest of the year than the other two combined due to third parties realising where the money is, as well as Nintendo's intention to stop announcing games a year before they're released.

PS3 has 20 great games this year all exclusive. The other two consoles mentioning them makes me ill.

 Except you don't know if any of them will be great or not. (Not yet, at least.) And most of them are first- or second-party titles bolstered by the Sony Hype Machine, which is very good at making mediocre titles look amazing. (See: Motorstorm, Lair, Heavenly Sword.)

I'd imagine a lot of people picking the PS3, therefore, have their opinions skewed by how much hype exists for Sony's titles. Both Nintendo and MS have a lot of great exclusives coming out this year; they're just not hyped to hell and back.
