Given that Sony plans to ship 5 million units this fiscal year, and the WiiU will pass that mark at Christmas... not before late Summer or early fall at the earliest. Sony sales have been great and may continue to be strong but it is supply constrained at the moment. Sales will slow until the PS4 games inventory improves after the initial fervour is over, it seems there is still pent up demand.
While the WiiU had a dismal year with a prolonged game drought and weak sales, the console has built up a good library and has good titles coming out that bode well for a respectable (but not wii like) second year. Sony has captured momentum in most markets with XB1 only making a large impact in the US/UK (and possibly a few smaller markets that I have missed)... they will do well.
Seam Machines will also enter the market in this time frame and starting at $499 may also have an impact.
