I seriously doubt MGS4 will sell more than Halo 3. MGS games breed raving fanatics, but don't have as a wide an appeal as Halo games. Halo is just easier to play and easier to get into (whether or not Halo games are better than MGS games is not the issue. MGS might very well be the better series, but Halo obviously has a wider appeal). MGS has never sold the way the biggest franchises have, though they've always sold rather well. I expect around 2.5-5 million for MGS4, with the install base hurting it in the short term and great legs.
Anyway, great PS3 exclusives:
1. MGS4
2. GOW3
3. FFXIII
...that's really all I've got. I'm sure there will be some other great ones, but I'm not willing to give IP's the benefit of the doubt until the game comes out. Maybe Ninja Gaiden Sigma. And, hey, Chrono Trigger 3 (a guy can dream, can't he? Hell, I'd probably buy a PS3 just for that game alone if it ever existed)
My consoles and the fates they suffered:
Atari 7800 (Sold), Intellivision (Thrown out), Gameboy (Lost), Super Nintendo (Stolen), Super Nintendo (2nd copy) (Thrown out by mother), Nintendo 64 (Still own), Super Nintendo (3rd copy) (Still own), Wii (Sold)
