Microsoft always has a middle of the road E3, in my mind. Although they do tend to focus too much on what's popular outside of gaming (exercising, TV, sports), they usually show some actual games, and aren't complete train wrecks (outside of the Xbox One, of course).
On that note, MS executive Phil Spencer took to Twitter recently to talk a bit about their upcoming showing at E3 this year, and said that the presentation would be around 90 minutes, will focus on a ton of games, and that there will be "very few execs" participating.
If all that's true, it's good news! We'll see soon enough.
