I've got a Wii U, because eventually Zelda will come, and that's a must-have. No question about it. I think there's enough out right now or coming soon to keep me entertained until Zelda comes too.
Not sure about other consoles. I want one, but they're not looking very good. The PS4 looks okay. Looks like they're trying to do as much as they can to make it appealing to devs and convenient for gamers, but there's a lot of bull shit too. Too much gimmicky crap like the "share" stuff and motion controls. But I think the worst thing is no real backward compatibility, at least not yet. There are quite a few PS3 games I never got to play that I would really like to, but I feel like it's too late or not enough to get a PS3. Being able to play them on PS4 would be a huge selling point, but it looks like that's not going to happen. This Gaikai stuff sounds pretty crap in my opinion too.
I used to think that the next Xbox would be a certain too because for me Forza is a must-have as well. As time has gone on though, it's starting to look very unlikely I'll get one. The rumours of what it'll be like sound awful. Even enough to ruin the experience of a game series that I've put far more time in to than any other. It still may only be rumours, but at this point they've grown so numerous as for them to be far more likely true than false. If so, then well done MS. You pushed me away from one of my favourite things in the world.
I'd like to get a PC, but I've been doing some serious thinking about it recently and I just don't feel like there's enough there for it to be worth the cost. But more importantly, I just don't really have the space to have one.
