I'll tap dance naked down my street if the Vita hits 60 million, lol. 

Handhelds are finished in the West. 

I think the even the 3DS will cap out around 85-90 million WW with a huge chunk of that coming from Japan. 

And TBone, Id recommend not including predictions from users with fewer than, say, 100 posts.People can sign up to just post for the sake of skewing the result.

i think i got like 2-3 people that are new, if they dont stay for a long time, i'll take them off!

vita 40 mil

wiiu 58 mil

ill check this thread in 6 years :p

Vita 24 million
Wii U 26 million

These are my predictions for total lifetime, not two years like the OP says.

Wii U - 54 mil
Vita - 28 mil

Cool that we'll have an "I told you so list" one way or another.

Is this for two years from now, or lifetime? Either way...

2 years from now...
