Note: I don't see any of these listed on Microsoft's official acquisition list. I believe this indicates these purchases are below a certain dollar threshhold so don't need to be included there. (I've asked to see if this is the case.)
At E3, Microsoft confirmed officially previous reports that there will be a successor to the current Xbox One console. Without disclosing timing or details, Microsoft officials said they are "deep into" building more Xbox consoles (plural), and that they'll include AI technologies to help make gaming more immersive.
Officials also said the company is still working to build a game-streaming service, The Verge noted. Last year, officials said they expected to deliver a game-streaming service within three years. No updated timing was provided at E3, but officials did confirm that the coming service will work across multiple platforms -- not just Microsoft's, and not just with gaming consoles.
