I honestly think both could do it, but I dont think XBOX will ever produce 100 mil as the 720 will be out before then. I think if PS3 is around for 8 or so years it may make 100 mil, even with the strong competition XBOX gives it.
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.
