Q1 last year for WiiU - 520k.

Things to note!

WiiU is down this week in Japan YOY 20k, a trend?

Microsoft may announce tier 2 release dates which may fall in Q1.

I'd say the Xbox One will sell more, even though it won't be out in Japan or some European territories by April (as far as I know).

Wii U has been selling a lot in Japan the last weeks, but I wouldn't be surprised if the sales spiral downwards to ~20k a week until DK is released. Wii U isn't selling in Europe and some of the games releasing in Feb/March will put the Xbox One further ahead in the US.

Isn't Wii fit U on January?

I think it's clearly obvious that the Xbox One will sell more. Not only because Xbox One has more software releases those months but because the Wii U is proving to be a incredible failure.

Wow, It's a tie.

For me it looks like the X1 has a clear edge here so I would like to hear what the WiiU supporters have to say.

Pretty even voting so far!! :)

I am gonna say x1

Well X1 has Titanfall... that alone will boost it above the Wii U...

Here is some good info.

First Jan - March for PS3 in the US

244,000
127,000
130,000

Total 500k

Can XB1 match that though??

wii u will
i honestly dont know anyone who even wants an xboxone. too expensive for the system and then online price the ps4/wii u is just a much better option and this is coming from a previous 360 fan

3 million people want one :P You shouldn't base predictions based on those around you, it's a drop in the ocean.
