I'm getting a PS4 for sure, but that's because I'm a PlayStation fan and I love Sony's 1st party devs like Naughty Dog. I'm open to other systems though, but I'll have to see what they offer. I had some mild interest in the Wii-U due to the Wind Waker remake, but the system it's self isn't really "next gen" in my book and I think it's going to end up being a disappointment in the long run.
I don't have much interest in the next Xbox either, but that's because I don't know anything about it yet lol. However I want MS to seriously change some of their business aspects, I want them to make XBL free and get some more exclusives. Just my opinion though.
I'm excited about next gen, I think it's going to be good for everyone.
