I think they're going to use RDR2 to show off how Scorpio will become the next best console for multiplats by giving us a trailer with insane visuals. So although it's fully playable on both machines, it'll still be Microsoft's "top game" from the presentation because it will shock the audience by how much better it looks on their high-end machine. Just speculation though! Obviously MS would need to spend some big cash for that (but they did that a lot during the 360 gen, so who knows?)

Cuphead! It's going for a streak.

No....Scorpio will have the better multiplats all on its own. They dont need an exclusive deal to do that. No offense, but Rockstar has never signed more deals with Microsoft than they have with Sony. Sony had  timed exclusivity during the PS2 era and Rockstar would never have given that to them unless they were winning. They dont need to show off how powerful a console is. They want the widest audience. Im sure the only reason Sony got bundling rights to GTA V was because they closed an eight million console lead that the 360 failed to hold on them or widen. It was a level playingfield. Sony has always had a working relationship with them because of that. Now Tomb Raider? That deal makes zero sense businesswise and yet it happend. It shows that Square Enix would take money our of desperation faster than Take Two ever would. I personally dont think there will be anything but bundling rights this time around and Microsoft would have to give Two a huge amount of money just to have bundling rights. I think they would be better off making a studio that can make AAA games for them at a high level. What they need right now isnt more deals, but rather a new IP to show audiences what their identity is all about.

Definitely Scalebound, Fable: Legends, and Phantom Dust. Literally the only three Xbox games I want.

Two were canceled and the last one, I believe is still on the list. 

M$ didn't have anything new to show last year, so I'm sure they'll have some surprises up their sleeves this year. I'm guessing they have a few big 2nd party games to show off, like a new Fable developed by... someone, a and probably a couple partnerships like Recore and Sunset Overdrive. Iirc M$ so far this gen has had at least 3 big titles each year. With no new Halo until probably 2018, and gears in 2019, they're going to need some new titles to push sales going forward. Crackdown and Sea of thieves will be their heavy hitters for this holiday, so we'll probably also see a lot of those two at e3.

I predict Bioware to come out swinging announcing Kotor 3 or announcing a "remake" of Kotor that fits into the official star wars canon. People will flip out hardcore. As will I. I just hope they release it on the Switch, because taking that game on the go would be amazing and connecting it to my projector, but I'll get it pc otherwise.

Probably something new with Minecraft.

For as many updates they give out for free - at some point you know they'll rake it in with a high profile expansion - especially if it's something they keep exclusive to Xbox One, Scorpio, or even PC for at least a little while.
