really doubt 360 or ps3 would have gotten much more sales without wii. i guess at least 50-70% of the wii buyers would not have bought another console without wii. the rest would probably split between ps2, 360 and ps3 (i guess at the launch time of wii people might have bougt more ps2 without wii too).
sales for hd consoles might have been 10-15% higher without wii, but i doubt there would have been that much changes to the distributions between ps3 and 360.
