PS4 - Have it
Wii U - Already planning to buy one. Hopefully, relatively soon. It will depend on deals if I get one this Holiday or not.
XBO - No interest, With a PS4, I don't see much need for it. With that said, I'm sure it's a great console too.
3DS - No interest. Had it, sold it, no regrets
PS Vita - I could use it as a streaming add-on. Maybe I'd consider it at $150 or so. Preferably, $100
