The only thing that could ever, ever make me even consider going back to Xbox would be if Halo 5 was amazing. Considering it's being made by the devs that made me lose all hope for the franchise I won't hold my breath. Halo 1-3 were the only reason to own an Xbox or a 360. Seriously what does Microsoft have if they don't have an EXCELLENT Halo title to support it. There hasn't been a good Halo game in 7 years. The worst part is most of the core Halo fans have abandoned ship after Reach and Halo 4. If Halo 5 isn't AMAZING like 1-3 then shit will really hit the fan for the Xbox One.
