is pretty incredible

no it's even close.

I'd put it roughly at NES, maybe slightly more.

Crysis 3 barely sold about 1m on PS3+360. Does that make it a niche title? No.

Just because a game doesn't sell well, it doesn't mean its niche. That is a factor but there is more to it. A niche title is usually a game that sells well despite being in an unpopular genre.

For example, Monster Hunter is only considered niche in the West. It's not only because it doesn't sell well, its also because that genre isn't very popular or recognizable.

So selling more than the vita and twice as much as the ps3 in japan is "bad"

Strong sales and healthy future: Yes, I can see it, a nice profit for Nintendo, a good collection of games and maybe 40-50 million lifetime sales.

Domination?
No, I don´t think it will happen, when the current gen starts to lose support, the WiiU will fell the pressure of more and more amazing titles that everyone wants but the system cannot have.

So, I still think the WiiU will have a respectable and solid third place, but with profit and corporate health for Nintendo, and, the best of all: good games for the fans.

Also, the WiiU is competing, again, with nothing on Japan right now, it is the only next gen console on the market, so, it better sell more than the PS3.

My reasons to doubt the Nintendo Domination are: GTA 5, huge game, I will buy, and other 15 million people will buy it, not on WiiU, this alone is a bad sign. Remember this: the PS3 WAS NOT in such a good shape when GTA 4 came out, and still it got a very nice port of the game.

GTA is the gamers game, the real deal juggernaut of the industry, Call of Duty is for the casual, for angry kids with ADD and adults with not much time to play. It is cool and it sells, but the real deal is GTA. Even the DS had one.

I really think Nintendo should be agressive about getting games like this, offer 5 or 6 million to the developer, help in the port, do something, but do not lose these really important titles.

Is that supposed to be some sort of accomplishment? PS3 is a seven year old console dying of old age. Vita is a sorry handheld that can't even maintain a decent level of sales after a price cut. This one "good" week won't do anything for Wii U in the long term regardless of how well it actually did.

Nope. Sales are going to drop like a rock to be hoest.

It still isnt enough, but things will get better as more exclusives release.

I'm gonna be honest. Looking at next year's line-up the Wii U seems like a more atractive purchase than a PS4 (not even gonna bother mentioning Xbox one cause thats completely ruled out). This cause i dont see FFXV beeing released on the first year in the west and KH3 will take even longer.

So, as far as im concerned i do see a rosy future for the Wii U for this holiday and next year. After that we shall see. A price cut will definitly help this fall.

Niche means it's targetted at a small specialized group or market. The success or failure of a product has nothing to do with whether it's niche or not.
