with a Maximilian avatar i thought you'd list White Knight Chronicles

While I'm a Wii only owner, of the currently announced titles I don't think Wii can be considered to have the best lineup (even if it more suits my taste). I would say PS3 seems to have the biggest games as far as followups to big titles and anticipated new ips.

Games I want with 2010 release dates.
Wii
Super Mario Galaxy
Metroid Other M
Red Steel 2
Sin and Punishment 2
Maybe, The Grinder, Epic Mickey, and Endless Ocean 2

DS
Okamiden

If I get a 360
Alan Wake
Splinter Cell
Fable 3

If I get a PS3
Modnation Racers
Heavy Rain

360: Alan Wake

PS3: GoW 3 + Collection, Heavy Rain, ModNationRacers,

PC: The Witcher, BFBC2, Mass Effect 2

Maybes: Dantes Inferno, Splinter Cell, MAG, White Kight Chronicles

Monster Hunter Tri
Red Steel 2
Epic Mickey
Arc Rise Fantasia
Sakura Wars: So Long My Love
No More Heroes 2
Tales of Graces
Super Mario Galaxy 2
Sky Crawlers
Final Fantasy XIII
Mass Effect 2
White Knight Chronicles
3D Dot Hero Game
Fragile
Arc Rise Fantasia
Mass Effect 2
Capcom Vs Tatsunoko

Off the top of my head

Yeah, I'm going to get White Knight. Just not for $70. The games i listed I intend to buy on launch.

If I can snag WKC for around ~$50 at launch I'll probably bite though.

Well me buying GT5 is a given. Its my only must have though.

I'm on the fence for GoW3, MAG and the other Q1 games.

For 2010 ps3 exclusive...

*WKC
*GOW3
*GT5
*Heavy rain
*Modnation
*Last rebellion

getting if released in 2010...

*Quantum theory
*The last guardian
*Agent
*Resistance 3

multiplats...
