Its simple.

Nintendo will own Japan, MS won't.

In America, Sony will be too busy fixing Vita. Plus, they have no exclusives and they are still releasing new PS3 entries of their biggest IPs (GOW MGS)

Europe? Nintendo will reach into more markets like they did for Korea this gen. Watch when they invade China.

Wii U will eclipse 115m. Take that for what you will.

I BELIEVE IN SAVIOR X. I am in no way affiliated to Savior X, nor did I log into my acount for the first time for more than a year to support him because he asked me too on Skype.

I'm pretty sure you are the one who needs to do the proving. Obviously no one can prove you wrong 2 months before the system is even launching

Or alternatively..

Motion control was an innovation, tablets no longer are. Nintendo consoles that haven't innovated have never sold over 50mil. 360 is rapidly catching up to the Wii in America and the PS3 is rapidly catching up in Europe. Nintendo is losing its dominance everywhere but Japan.

Wii U will sell much worse than the Wii. Prove me wrong.

Really?

Wii U the 'new' PS2 confirmed.

What do you mean Sony has no exclusives? Are their 1st party studios just sitting on their hands with the PS4?

Well, I don't think we can throw around numbers yet based on the fact that we don't know enough about Durango or Orbis.

Totally agree on Japan, though. That country will be Nintendoland (yes, pun intended) for the 8th generation, and I think that WiiU will make consoles relevant there again.

Yes, I think Nintendo will prove to be the victor next gen (in both install base and profitability), as they pit Microsoft and Sony directly against each other for second place.

okay. I'll rephrase that. They were the first ones to make a good motion control focused console... I consider innovation the first people to make something work well, which the eye toy clearly didn't... 

Brilliant!

Perspective. 50m in itself means nothing, being decades ago. SNES was actually a pretty decent success; it maintained more than 80% of its predecessor's sales, with much, much stiffer competiton; in fact, the fifth generation was probably the most competetive ever, with the Sega Genesis managing a very comparable 40m.

Also, if we bring handheld sales into this (I don't see why not; it's the same industry), Nintendo's non-"innovative" GBA managed over 80m against less than 120m for GB. The thing here is that Gameboy sales include GBC, which was a fairly big deal graphically, meaning a significant amount of people probably upgraded, making the userbase not more than 80-90m at best. Also, GBA was killed very prematurely (its successor launched three and a half years after it) when it was barely hitting its stride, so it probably would've done a lot more.

Looking at this kind of precedent, I'd say it's very likely that WiiU will do about as well as Wii, since competition is likely to be much weaker, given Sony's financial state and the Vita, and there's no reason for WiiU to be killed prematurely by a successor.
