Let me list what games I'm planning on getting for the second half of 2009/first half of 2010.

Wii

Super Mario Galaxy 2
New Super Mario Bros. Wii
Sin & Punishment 2
The Conduit
Red Steel 2
Metroid: Other M
Wii Sports Resort
No More Heroes 2: Desperate Struggle
Resident Evil: The Darkside Chronicles
Arc Rise Fantasia
TMNT: Smash Up (possibly)
Final Fantasy Crystal Chronicles: The Crystal Bearers (possibly)

DS

Pokémon Soul Silver
Mario & Luigi RPG 3 (possibly)
Golden Sun 3 (possibly, depends on if I like the second one or not, only played the first so far)

X360

Assassin's Creed 2
Alan Wake (possibly)
Splinter Cell: Conviction (possibly)

PC

Starcraft II (If it releases in said timeframe)


What about you guys?

Wii:

• New Zelda with motionplus support
• Super Mario Galaxy 2
• Metroid: Other M

PC:

• Starcraft 2 no matter when it is released.

Xbox 360:

• Natal if there is some awesome killer app for it. 

I'm interested in a lot of other games, but those are the ones I'm most interested in.

Long list and I don't know which ones I'm planning on buying but these ones are on my radar:

Wii

• Metroid: Other M (or whatever the bad name is)
• Super Mario Galaxy 2
• New Super Mario Bros. Wii
• The Conduit
• Red Steel 2 (I won't touch it until I see reviews but I'll keep an eye on it at least)

DS

• Mario and Luigi: Bowser's Inside Story

360

• Alan Wake
• Left 4 Dead 2
• Crackdown 2

PS3

• New Kart Game
• Fat Princess
• Final Fantasy XIV
• The Last Guardian

The Last Guardian, for sure.

I'm surprised to see the big Wii lists that don't seem to care about Zelda + motion plus.

Gow3
Uncharted 2
Tekken 6
Ninja gaiden sigma 2
Modern warfare 2
Final fantasy 13
Ratchet future 2
White knight chronicles

Just to name a few.
