IMO still too early to predict, depends from numbers of revisions and how long life span, IMO definatly 80m+, but where could end up really I can't really tell yet, I voted for 81-95 millions option.
Kinda agree with this, still too early, it's a fairly young console.
For the record; I chose the same option, 81-95 million. Interesting that over 80% believe it'll sell 100 million or more, seems like a lot of fairly high expectations for this machine. It has good appeal, but still needs constant attention to maintain momentum, let's give Nintendo at least another two-three quarters to show their mettle and what they have in store for us. Regardless of lifetime sales, I'm glad it's doing well and offering something else, like I said throughout the 7th gen; I dislike complacency being rewarded (in regard to the relatively impressive PS3 and 360 sales).
