MS and Sony Fans! What would it take for you to buy a WiiU?

Somebody capable of destroying my backlog. I already want Pikmin 3 and SM3DW but I have so many games to play on PS360, PC, 3DS and PS4 that I have no reason to drop $300+ on a Wii U. I may not be able to resist once MK8 comes out though.
