So with launches to the end of Q1 it looks like WiiU sold about 2.87m units and  for comparison's sake PS3 did about 2.86m units. 360 was around 2.42m in the same time frame.

lol so basically a statistical tie with PS3. But the title is more fun with WiiU winning. :)

Still, Nintendo will like have a very low 3m shipped figure and definitely no where near their already lowered 4m forecast. However, sales have picked up now that games have finally launched and hopefully that will continue.

So now where will Q2 land?

Depends on Software what does release in Q2 ?

Q2 = April, May, June.
Injustice: Gods Among Us
Dues Ex: Director's Cut
Resident Evil Revelations
Sniper Elite V2
Pikmin3
Wonderful101
Game & Wario
Wii Fit U
LEGO Batman 2: DC Super Heroes

This is not including various eShop and VC games that are also coming as well as games that I am surely missing/forgetting like movie tie-ins etc.

What is that PS3 boost? Euro late launch or some kind of price cut or game release?

It is certainly interesting that Wii U performs better than PS3, but comparing PS3 to Wii U seems a bit unfair. PS3 had every odds stacked against it (its own price, 360's and Wii's success, etc). The Wii U has pretty much no competition and can't seem to take off for now. We gotta hope it will improve before PS4 and X720 arrive and leave it in the dust.

Yes, it would be interesting to see GameCube vs WiiU data over spec give life time.

Wii U started pretty good. To bad it deflated very soon.

Yeah, PS3 launched in European and Australian territories in March.

WiiU has competition... no different than PS3 did. PS360 is quite the sustainable duo still.

That's a very weak line-up in my opinion.  Multi-plats won't sell systems.  Pikmin 3 might sell a few 10ks.   Wonderful 101 won't sell any systems and I doubt Game & Wario will either (but should sell well to existing base and new owners).

Wii Fit U - If Nintendo is expecting this to save WiiU I think they are very badly mistaken.  Wii Fit was a fad (even moreso than Wii Sports) in an industry (exercise/diet) prone to fads.  But that fad is long since over and everyone already owns Wii Fit(Plus).   If they hope to convince any soccer moms that they want to shell out $400 for a WiiU/Wii Fit U they'll have to prove it's far more effective than Wii Fit was, and be VERY clear it's not on Wii.    This game (and system) should have been out in 2010/11 to have had any sales potential.   It's far too late now.  With Wii, games like this helped convince mom's to get a Wii for everyone to enjoy, but they are not going to get a WiiU for themselves and their kids aren't asking for WiiU's.   

I expect trepid Wii Fit U sales followed by endless WiiU is doomed threads.    WiiU's sales this quarter should be better than Q4 but still far below 360/PS3 respective launch sales.

I want to buy 6 of those games.

Its not weak. When combined with what's out already it adds to a growing and diverse library. That adds value to a potential buyer who is waiting for not THE one game to get the system for but a combination of many games that make the hardware cost worth it.

So Q2 ends the last day of June?

I think Pikmin 3 might be able to take it over 360/PS3 at this time, but purely week to week I'll think it would have trouble matching the 360's 400k each week. I could see it hitting 800k the month Pikmin 3 releases... Not just for Pikmin 3, but simply because Pikmin 3 comes as an excuse to jump on board to people that were planning to buy one anyways.

Wow, turns out it was a late European launch in the middle of March, I just assumed it was an international launch...
