115 million.

damn you're guessing for some long legs for current gen.  I guess there's still price drops to come for the HD twins but isn't PSP still pretty far away from that?  Also I guess Wii can still get a slight bump from $99 price cut but it's already pretty affordable unlike the HD twins which are still $200 for their least expensive crappy models.

I'll say 80 Million.

My prediction is missing. This is actually a serious prediction, 169 million.

107m

Vita will sell more than WiiU LOL

The PS4 will win the upcoming generation, but the industry as a whole will shrink. Also, to the common folk, the PS4 doesn't offer much new (like DVD and Bluray), which will hurt the industry further. I'd say somewhere between 80 and 100m, which should put it comfortably ahead of the WiiU and XBox One. For this thread I'd say 89m.

120m seems doable

I'm going to go a little crazy here and say 165 million.

100 Mil!
