what are you saying? Neither will pass xbox, not even close.

Oh wow i just realized Vita is outselling the WiiU

Holy....

I doubt either will reach the sales of the original xbox though.

Can the Wii U beat the Vita? Possibly, and now more likely due to Sony dropping support in the West.

Can the Wii U/Vita beat the Xbox? No.. unless you mean Wii U + Vita?

The Wii U is starting to outperform the Vita in Japan alone thanks to Splatoon, so I could see it catching up and overtaking the Vita.

Other than that, I don't think it's possible unless Nintendo stretches the Wii U for many, many years.

Only if you mean Wii U + Vita.

It's currently had a sales spike from Splatoon. We need to wait and see if Splatoon has created a new sales baseline for the system before we know if it will translate to outselling the Vita long term.

There's a few big Vita titles due to drop in Japan soon though which could put things back to exactly how they were prior to Splatoon.

...You mean PSV+WU > XBOX ??? :|
Or what? If you say combinet, will happen for sure, i don't see how can WU+PSV sell under 30m, and XBOX sold under 25m.
If you say only WU / PSV , i doubt, expecially PSV....................... WU will sell under GC and the GC sold under XBOX.
And the PSV is not going to sell much more than the GameGear, and the GameGear sold only 11m...

combined sales? possibly.
one of them? nope.

Wii U won't beat Xbox.
Wii U won't beat PS Vita.
