I'll take mrstickball's list and modify it. I'll stick to consoles:
Xbox 360:
Mousou Orochi
Halo 3
Lost Odyssey
Playstation 3
Blade Storm
White Knight Story
Gran Turismo 5 Prologue
Samurai Warriors 6
Nintendo Wii
Super Mario Strikers Charged Football
Super Mario Galaxy
SSBB
Playstation 2
Final Fantasy XII International
Musou Orochi
Fatal Inertia is most deifnitely not a system seller, neither is Oblivion for PS3, Or Eye of Judgment or Ace Combat games or Hot Shots Golf on the PSP.
White Knight Story and GT 5 Prologue are the biggest 1st party games for the rest of the year in Japan for the PS3. Bladestorm and Samurai Warriors will also move PS3s, especially the latter.
The 360 will have a decent boost from Halo 3, Musou Orochi might sell some systems but it's also coming on the PS2 so that won't be much of a big deal. Lost Odyssey is the biggest 360 seller for the rest of the year in Japan and should give a similar boost as Blue Dragon.
Wii has 3 games that will sell lots of systems, especially SSBB and Mario.
Thanks to Blacksaber for the sig!
