Probably Halo 6. They will also announce forza 7 and Ori 2. Hard to see where other new big announcements come from, but I am sure there will be at least 1 surprise.

I hope for MS sake that Crackdown 3 is not their main exclusive this year, because it screams mediocre to me. Probably will put Halo 6 beta with crackdown 3. I can see them also delaying full release Sea of Thieves to 2018 with beta end of 2017.

Cant wait to see more State of Decay 2.

I expect a new IP to surprise everyone at the show

Halo 6, Forza 7, Crackdown 3 and a wildcard title (maybe Fable 4?).

A new Halo. But mark my words, it won't be called Halo 6!

Just hoping for something half decent, Sony have been the kings of exclusives this gen and its getting embarrassing....

Halo 6 native 4k 60fps

Microsoft is not pushing it with their first party unfortunately....

BUT, they killed attack with banjo 3 ;)

Battletoads ;)

Halo 6

I don't even know if MS have any major studios whose projects aren't known.

Any big surprises would have to be bought from a third party
