I think that Sony gives more access to the hardware to their first parties. It helps differentiate them from third parties and guarantees that Sony made exclusives look better than other offerings, drawing more people to the platform. I also think the other 2 brands do so as well.
My question to you is do you thing that PC multiplats are being gimped for PS4's sake. Sony probably has a clause that says the Microsoft PC platform games can only look a little better than the PS4 version.
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.
