Microsoft, as always, had quite a bit to say. Here's the gist!

Xbox Hardware and Xbox Live

• Xbox One S: A slimmer version of the Xbox One, launching in August for $300.


• Project Scorpio: A totally new console from Microsoft, coming in 2017. It's capable of 4K gaming. Microsoft says this is the first step toward their plans for incremental console upgrades. New consoles will be able to play older games, older consoles will be able to play new games, but at lower quality.


• Custom controllers: Microsoft is launching a Design-your-own controller service, with 8 million possible combinations.


• Xbox Play Anywhere: A program that lets you buy a game once and play it on Xbox One or PC, with synced saves and achievements..


• Xbox Live Multiplayer: Three new multiplayer features were announced. Clubs, connecting people with similar interests (like Steam groups); Looking for Group, which lets you seek out multiplayer buddies for games; and Arena, a new tournament platform that lets people compete across the world.

Game Presentations
It's important to keep in mind in these early announcements that many games that say "coming to Xbox One" may also hit the PS4. They just won't tell you that at the Microsoft conference. One thing I love, though, is how many of these say "and PC." Though it may require buying them from the Windows Store :/

• Gears of War 4: Horde Mode is coming to GoW4, and the campaign will be a return to the classic style.


• Sea of Thieves: Rare's new pirate game has a new trailer, and it looks Swashbuckling.


• Scalebound: Platinum Games title that involves killing dragons? Sign me up! With co-op to go dragon slaying with friends.


• Recore: Launching in September on Xbox One and PC, this Keiji Inafune title is a robot action adventure game with some intense platforming and a lot of charm.


• Final Fantasy XV: It's still weird to see Final Fantasy on the Microsoft stage. A demo was shown, and it looks pretty incredible. The battle system seems far more action-oriented than previous games, but that's not necessarily a bad thing. The series can't keep doing standard turn-based ATB battles and stay relevant.


• Dead Rising 4: Coming holiday 2016, and set during Christmas.


• Forza Horizon 3: Absolutely beautiful, as all the Forza games have been. This seems to really be pushing the tech. This supports cross play between Xbox One and PC.


• Halo Wars 2: Coming February 21, 2017. It looks a lot like Starcraft in the Halo universe, and that's about the best compliment I could give a sci-fi RTS. There's a beta out today on Xbox One.


• Gwent: If you played The Witcher 3, you probably played the in-game card game, Gwent. It's getting a standalone release for Xbox One and PC.


• State of Decay 2: Coming in 2017 for Xbox One and PC.


• Minecraft Realms: A multiplayer cross-play powered Minecraft, that lets you play on Xbox One, Windows, and mobile platforms, as well as Gear VR. It also has dedicated servers, which is a biggie for the Microsoft versions of Minecraft.


• Limbo: Currently free for a limited time.


• Inside: Coming in June for Xbox One and July for PC. A new title from Playdead, the developers of Limbo. It looks kinda dark and twisted and amazing.


• The Division: Underground DLC coming this month, first to Xbox One. Stupid timed exclusives.


• Tekken 7: Coming to Xbox One and PC in early 2017.

Phew, that's a lot.
