my predictions.
by end of 2008: ps3-17M 360-24M Wii-50M DS-95M PSP-40M
No More heros - 500k
SSBB - 10+ M
Mario Kart - 10+M
wii fit - 10+ M
GTA - 7-8M across both platforms (ratio will favor the 360 by 10% better than hardware ratio at release)
MGS4 - 1-2M assuming is stays a ps3 exclusive
Killzone2 - just barely 1M
Halo wars - ~1/2 that of halo3 so like 2.5M
eh, that's all that comes to mind right now. oh, and software numbers are LTD numbers.
