While the conference isn't until next week, Microsoft has revealed their big news a week early.
Now that they've officially announced that they're opening their Xbox Live framework to iOS and Android game developers, and in tandem with Project xCloud, it's clear that they want their fingers in as many pies as possible, instead of keeping things locked down to their own platforms.
Microsoft wants to bring the Xbox Live experience to two billion gamers around the world, so they're launching a new developer's kit that will make it easy for game makers to integrate some of the key Xbox Live features into mobile games.
The new Microsoft Game Stack unites services such as Xbox Live, Azure, Visual Studio and PlayFab, the Seattle startup Microsoft acquired previous year. "The goal of Game Stack is to help you easily discover the tools and services you need to create and operate your game", saidKareem Choudhry, Microsoft's head of gaming in a blog.
As Microsoft prepares for the next generation, the Xbox brand is expanding.
Choudhry remained tight-lipped when asked about the prospects of seeing Xbox Live on rival consoles, but reiterated Microsoft's desire to keep building bridges.
Rumors have been swirling for some time that Nintendo and Microsoft were up to "something" and while it was initially rumored that GamePass was headed to the Switch, Xbox Live integration may make a bit more sense.
What we do know now is that this Xbox LiveSDK will bring trusted game identity security controls and will allow developers to pick and choose which Xbox Live features they want to include in their games.
It's worth noting that a few games on mobiles already use Xbox Live for multiplayer - like Minecraft. Today we got the official announcement. but Nintendo Switch support is mysteriously missing. Does that mean we'll see Xbox Live better integrated on Switch? "Phil [Spencer] has been very proactive on issues like cross-play, cross-progression, and uniting gamer networks, and we're willing to partner with the industry as much as we possibly can".
