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.

This is exactly the kind of game that isn't a blockbuster, especially in Japan. It has a better chance of doing well in the US, but I don't expect it to be huge because it's very non commercial and too out there for most players. It will do better than Killer 7 cause it's not as unplayable as that but it won't be big.

All that said, this is the 2nd most anticipated Wii game on my list only surpassed by Mario and that's saying a lot for a 3rd party game on the Wii.

so nobody think that beautiful Katamary is a big licence in japan... I'm personally not interested in that game, but to my belief a lot of website are seems to say that the little ET is over famous over there... am I missing something ?? ?

heavenly sword..

the biggest titel in japan should be dragon quest IX. i expect the ds to really skyrocket in the last quarter. (it is coming this year isn't it?)
