Wii U has the best console line up for the next two years. If you have a gaming pc, outside of that ps4 game i forgot that starts with an H, most noteworthy titles will be available on steam or even ps3. Little reason to buy a next gen console unless you prefer playing on consoles and want your games to be more expensive and look worse. Other wise, stick to pc. PC also has better exclusives. More than that, we all know xbone's "exclusives" are also coming to pc for the most part. It has already lost Titanfall and Rome or whatever it's called. Wii U however has exclusives that seem fun, and different from usual AAA claptrap.
So if you're going to buy a console, Wii U seems like the best bet.
Doesn't help that Nintendo "won" E3.
