Here's my predicted breakdown of lifetime wii u sales. What's yours?

NA-8.3m  EUR- 4.0m  JP-4.2m  ROW-1.5m

Total-18m

NA: 9,000,000

EU: 6,000,000

JP: 3,500,000

WW: 20,000,000

Also, why you think that in Japan will sell more than in Europe?
That not going to happen...

If it stays on the market as a platform till 2017 /18 then i predict.But this could all change if at E3 they have nothing new other then what we already know about.

Japan = 5.2 Million
Europe = 6.7 Million
North America = 10 Million
Rest of the World = 1.3 Million
-------------------------------
Total 23.2 Million life time sales.

But if Nothing new for E3 this year then i expect it won't sell much more then 15 Million world wide..

Nintendo it's in your court..

I'll be surprised if they beat GameCube numbers

Well Japan is leading Europe at the moment according to vgchartz. 2.2m to 2.1m.

it depends on the price at the moment. could still be below 18M. but i was hoping a price cut would come this year and another maybe late next year or early 2017. those would help the transition. i'll save my prediction until E3 to get a gauge on what Nintendo really wants to do with Wii U. hopefully a price cut for several people who wanted a Wii U but just think they need a little bit of a price cut.

i have Wii U already so i'm already part of the 9.x m owners. :)

Well Japan is leading Europe at the moment according to vghartz, 2.2m to 2.1m.

Look the 2014 sales.

Europe: above 1,000,000

Japan: below 600,000

The gap is 100,000, so, the Europe sales will pass the Japan sales very son.

Even GC and N64 have sold more in Japan than in Europe the first year's.

I'm certain that they will have something new, this is only wii u's third year so they have to support it or they will lose consumer confidence for future products.
