Why do u believe PS4/One will outsell Wii U by March 31?

[JoeTheBro]

Supply issues will keep the Wii U afloat as the best selling next gen system for a considerable time. Even if it ends the fiscal year with 5.5 million sales, the PS4 physically can't pass it this year. I'd guess May is when the PS4 overtakes Wii U.

Kinda doubt xbone will ever beat it.
