Pre-E3 rumors begin! Microsoft's conference lineup leaked (rumor)

I don't think Halo 5 would release this year anyways. It would be way too soon and 343i isn't that big of a studio. They can still show off something though. Won't be any gameplay, but a teaser or something, yeah.

Though I could be very wrong. It is possible to have multiple studios working on a game.
