Rumor: Halo Wars 2 Beta, new Battletoads & new E3 Trailer for today!

A reddit user on /r/XboxOne got a glimpse unto Xbox’s API and we have got some great information that may or may not be true!
“A trailer for Xbox Daily and the Xbox Media Briefing will be published later today by Microsoft. It’s already available on their servers. ”
SPOILERS AHEAD – BE ADVISED
The user dieklobrille says the following:

• Rare is working on a new Battletoads along with Sea Of Thieves which will not be a straight MMO but rather a The Division/Destiny alike.
• Forza Horizon 3 should be set in Australia.
• In Killer Instinct, General RAAM from Gears Of War franchise is set to arrive soon.
• A new Age Of Empires game.
• Zombie online game by Microsoft probably a new State of Decay or a new Dead Rising could be in development by Capcom.
• Halo Wars 2 beta is a thing. (Kinda expected since Bonnie Ross said all future Halos would have a beta)
• Anniversary update will gets its own landing page on Xbox.com with the major features listed, probably “available now” at E3 for preview.

He also states “seems like Microsoft will give Sea of Thieves a huge focus, cross-play, cross-buy”.
This is all he could get from the API, and had no additional info on Hardware.
There are a ton of rumors heading into E3 such as the Xbox Mini and the Scorpio which all seem legit. We shall see what is real or not.
