Everything you need to know about the PS4 vs. Xbox One battle? I'll tell you everything you need to know right here: Xbox owners are buying the Xbox One, PS3 owner are buying PS4s. PC gamers couldn't give a rip either way. Taa Daa!
So, should you upgrade? The answer is "probably not yet." (For PC gamers, the question here is "should I move over to the living room?" but we're not even going to attempt that debate here. If you enjoy playing on PC, please continue to do so.)
