What are your figures for install bases at end of fiscal '08-09? The Wii will probably lose some share over Xmas, but make it back in the quarter directly after that.
If my end '08 predictions come true (Wii looking doubtful for just 9 months though?), then Wii will squeak in with a 50% ratio:
Wii - 45m
PS3 - 19m
360 - 25m
Wii does need to sell 20m in 9 months though, which is almost an average of 500k/week. Might need to sell 10m over Nov/Dec to hit this (average 1m/week over 10 weeks).
