Ill guess the minimums in a lifetime as follow
x360: 37.5 mill
(since it sold rough 10 mill now, lifetime 3x longer + pricedrops and killergames)
ps3: 30 mill
(they dont sell as much atm but when they drop the price a bit wich eventuellay will happen i see people have money reserves bought wii already and think its accepteble to buy a ps3 aswell (assuming ppl with a x360 dont buy a ps3 because its roughly the same)
wii: 42.5 mill
(its exploding at the moment sold out everywhere and the hype is very high makes it a wannahave item no matter u like it or not, but the sooner the later i think many people will not buy it anymore because the games arent to spectacular and since many people are graphicwhores they dont want a wii anyway. but enough people wanting one and the cheap price ill say 42.5)
endings ill say
x360: 45 mill
ps 3: 50 mill
wii: 65 mill
p.s: someone posted that the ps3 wont do well thanks to the shareholders and they will make a new ps4 by that time.
imo all 3 are already making new ones :)
life isn't complicated, just face it simple.
