I think if PS4 wasnt doing so great they would have focus on the Vita. Since the PS4 is flying off the shelves they are happy to write the Vita off as a loss and are focusing %100 on PS4. Not implying that PS4's success is directly causing Vitas death but it is preventing Sony from caring about it dying off.
Getting an XBOX One for me is like being in a bad relationship but staying together because we have kids. XBone we have 20000+ achievement points, 2+ years of XBL Gold and 20000+ MS points. I think its best we stay together if only for the MS points.
Nintendo Treehouse is what happens when a publisher is confident and proud of its games and doesn't need to show CGI lies for five minutes.
