Don't forget Mario Kart is coming out about the same time as GTAIV, however that's still the best bet either PS3 or 360 will have for a while to beat Wii.
MSG4 week maybe for PS3. FFXIII for sure IF it comes out this year and assuming no AAA game for Wii to compete with.
I don't think 360 has a single other game that could boost sales enough this year outside of GTA.
