Halo 2 anniversary? Halo 5? or, although I haven’t seen this talked about, it is quite possible there might be a Halo 4 expansion (much like Halo 3 and Halo 3: ODST).
And do you think Halo 2 anniversary will be released on xbox360, considering they’re already releasing Halo 5 (aka Halo Xbox One) on XB1 as exclusive but saying they’re giving continued support of xbox360 with over 100 games to be released.
Cannot wait till E3 june, so wanted to speculate about it now 
Well, apparently OXM ( Official Xbox Magazine) in the UK has Halo 5 on its front cover. But 343 is saying they haven’t confirmed a name yet. I honestly think If 343 did Halo 2 anniversary for Xbox one only, it would be a bit of a console seller. And then if that happened, 343 would bring Halo 5 in 2015. But all in all, 343 said we will be getting a Halo game during 2014.
What it should be: Halo Wars 2
H2A is the only right answer.
That Magazine cover for OXM is fake,the real one has Alien:Isolation on it.Halo 2 Anniversary is almost bound to happen this year,And the next Halo after Halo 4 in 2015.
