Well, that's debatable. Microsoft have said "Halo on Xbox One" is definitely coming 2014. If that's some cheap way of selling a delay by replacing it with Halo 2, then that is one damn sucky move.
I guess you weren't here for the ntkrnl Wednesday banazaa last week? If all that holds true, H2A will be this year with a Halo 5 beta included if you buy it with Halo 5 coming next year. Also, that was supposed to be revealed at the end of February/early March which would lineup with April's cover story.
