Both, eventually, but only PS4 near launch (not pre-ordering this early, so I'll get it when I can). It's just a better value at $399 and the people in charge of the platform seem to actually know what they are doing. Not so sure about the decision-makers at MS. Still, I think the XBOne is an interesting device and I have a long history with some of its exclusive franchises. At some point, i expect that a price cut, exclusives I'm interested in, or unique platform services will probably move the value needle enough to make me get one. But as of now, they haven't convinced me that their software makes up for the better hardware in the PS4 and the $100 price premium clinches it.
