In Japan the Wii U should do well, they don't have Microsoft to worry about, they have 2 of the bigger third party franchises basically exclusive (though the DS/3DS seem to get the "main" Monster Hunter and Dragon Quest games while the Wii/Wii U have settled for the side versions ... DQIX is 4 million seller, DQX is probably going to be a 500k seller, so big difference).

Also Japan doesn't care as much about high end graphics, they have a full year head start over Sony.

The system should do well. The only big concern I see is that post-January lineup for Japan does not look very good.
DQX is OK, but being a MMORPG really limits its appeal, and Pikmin was never a big seller in Japan.

They could really use a Mario Kart for next March-April, but it probably won't be ready until fall at the earliest.

Wii Fit may be one of those things that people have had their fill of, like Nintendogs and Brain Training declining massively on the 3DS. 

So that's worrisome they need something stronger from Jan-June next year. 

EDIT: My memory is a bit hazy but I remember the N64 having a huge launch in Japan, like close to 500k sold, but the system dropped like a rock after that with no games but Super Mario 64/Pilotwings/and a Mah Jong game for a long time. 

The Wii U would have likely sold more if it wasn’t for limited availability

I was looking for a percentage tbh, any sources?

Nope you won't get percentages until Media Create/Famitsu most likely. 

The "word on the street" is that you can still find a Wii U in Japan if you really look for one, but supply is fairly scarce. So it's not a hard sell-out like the DS, PS2, was, but it's not a "definitely not sold out" like the 3DS (impacted by the Japanese earthquake), GameCube, PS3, etc. were. 

These numbers don't really mean anything....just look at the Vita launch, its was pretty good but look how its doing now.

Anyway Japan shows the same trends as USA and EU....3rd party isn't selling.

I was hoping for some early leaks really :P

Thanks for the reply :)

Worldwide? Unlikely. Europe launch was horrible.

I'd say it has a chance to pass USA Vita sales though. Maybe in Japan too...it really depends on 2nd week sales though. Too early too tell.

I dunno I'd say that Monster Hunter attach rate is pretty good, given that it's basically just an up-resed 3DS game slapped together for launch. Basically just free money for Capcom. 

Things like Tekken are just dying franchises unfortunately, they bombed on the PS3 in Japan, and the Wii U wasn't going to save them with a newborn sized userbase. 

They shipped 300k for the launch but added a further 200k for the reminder of the June launch month.
