Why does anyone care about destiny, looks like another generic shooter. Halo has got that whole nostalgia(people are raving about being able to play Halo 2 online again) thing going, I never got it. Also Destiny is cross gen and therefore makes moving to a new console a harder choice.
Im not sure your prediction will come true because you are comparing a launch week in September compared to November. Holiday boost alone gives X1 an unfair advantage. You will have people buying X1 for Halo that week+people buying X1 as a gift for the holidays. PS4 wont have that advantage.
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.
