I haven't been a single console owner for over a decade.
I'm definitely getting a Wii U at some point this year, and I'll get either an Xbox One or PS4 next year. There's more than enough coming to 3DS, and next month will clarify what's in store for Wii U, PS4 and Xbox One in the next 12 months or so. I still don't see myself jumping in at launch for either PS4 or Xbox One, though. I think it's worth waiting six months or so.
