For me its sadly.

1. ??????

2.??????

3.??????

4.??????

5. PROFIT!!! 

1. MGS4
2. SOCOM
3. Resistance 2
4. Bioshock (if it does come out to PS3 and is at a cheaper price)
5. LBP (if it lives up to the hype)

I would get Gears 2 first day if I had a 360, but oh well.

1. MGS4
2. Valkyria Chronicles
3. Fable2
4. Ninja Gaiden2
5. Tekken 6 (?) / Street Fighter IV (?)

1. Gears of War 2
2. Metal Gear Solid 4
3. Ninja Gaiden II

and if Resident Evil 5 comes out this year, there's is no doubt i will be picking that up day 1

Probably only Soul Calibur IV, and maybe not even that. I'll probably get a shooter or two like Resistance 2, but not on the first day. If Half Life 2: Episode 3 came out this year (which it won't), I would buy that on the first day. Oh, and Starcraft 2 would be another one as well, but I don't think we'll see it this year either.

Probably the main reason for the shortness of my list is that I buy most of my games second hand after the price has already dropped. So to sum up:

1. Soul Calibur IV
2. HL2: Episode 3 (probably won't happen)
3. Starcraft 2 (probably won't happen)

1. Left 4 Dead (though of course I'll pre-purchase it on Steam and probably be playing the likely beta a month before its release hehe)
2. ? Maybe Mirror's Edge if it turns out well.

The rest of my games will be bought on whims as most of my games are hehe. 

Gears of War 2
Metal Gear Solid 4
Little Big Planet
Resistance 2
The Last Remnant (If it sees an 08 release)

1) Tales of Symphonia
2) Kid Icarus Wii
3) Spore (PC)
4) Starwars: The Force Unleashed
5) Whatever the big gun Nintendo is saving for E3

Spore
Okami
Pikmin 3 (if it comes out this year)
...

Can't think of anything else, Nintendo is just too tight lipped.

1. Tales of Symphonia 2
2. Fragile
3. Ninja Gaiden 2
4. Metal Gear Solid 4
5. Dragonquest IX
