I still haven't purchased a current gen console because of the small amount of interesting games for them, but it's starting to get interesting now. Since the One with Sunset Overdrive is currently the equivalent of $300 and the PS4 without anything the equivalent of $380, the One is currently more attractive. That comes on top of the battery time of the DS4, which I very much dislike. I'm waiting to see how Bloodborne turns out before making a decision.
Interestingly, I never seriously considered the Wii U before reading this topic. Nintendo's line-up is of course very strong, especially regarding games I can play with my girlfriend. I might actually go for that instead and just keep my 360 on the side for the time being.
