I'll get a PS4 when a Sonic game comes out for it. But right now, all the PS4 has going for it fot my interest is Arkham Knight. One game isn't really worth it.
Man, I love my Wii U! I'm pumped for Smash(if you couldn't tell) and I'm enjoying Mario Kart 8 right now. I'll probably get Hyrule Warriors on launch as well, since it looks like it's shaping up to be pretty great. I hope we see some of those collector's editions over here though...
I'm really thinking about getting the Wii U. I NEVER buy consoles on launch because there's usually no games for them except a free game that comes with the console.
