I'm really not seeing any point in getting any other console besides my PS4 right now or for the next couple of years, it just has so many games that I want to play, either released already or coming over the next 12-24 months. I've not been able to buy many games since I got it at launch, hopefully I'll be financially better off soon and able to get some more, but I'd rather take the money that I could potentially spend on new hardware and use that for all of the games I want too play.
Time is also another consideration, when I have limited free time to play games and I have one platform that provides me with the place to play basically everything I want to play through this gen I see no point now or in the next 12-24 months in buying anything else.
I finally bought Tearaway Unfolded, which IMO is brilliant, so much fun, I have The Witcher 3, which is still in it's shrink wrap that I bought Christmas Eve (been running around to family and friends a lot, which is obviously more important than gaming).
Need to get Bloodborne, I want Ratchet & Clank, Uncharted 4, Horizon, The Last Guardian and tonnes more PS4 exclusives, plus there's a boat load of other multiplats I need to buy when money and funds allow.
I also have a Vita, which has games I still want, so yeah, other platforms seem really pointless too me this gen, right now at least.
