Microsoft is preparing to roll out new development tools that allow for cross-platform play on Xbox Live on mobile devices as well as Nintendo Switch.

That's according to a - now edited - talk listing for GDC, as spotted by Windows Central, in which the Big M appears set to announce a brand new SDK which will let users on the aforementioned platforms play on Xbox Live with PC and Xbox One users.

"Xbox Live is one of the largest, most engaged gaming communities on the planet with decades of experience providing managed game services to developers that save you time and unlock all of the social and engagement features that players love," the listing read.

"Now Xbox Live is about to get much bigger. Xbox Live is expanding from 400m gaming devices and a reach to over 68m active players to over 2bn devices with the release of our new cross-platform XDK.

"Get a first look at the SDK to enable game developers to connect players between iOS, Android, and Switch in addition to Xbox and any game in the Microsoft Store on Windows PCs."

This feature set is going to be using PlayFab, the backend specialist that Microsoft bought in January 2018.

Moving into the next console generation, Microsoft is positioning its Xbox Live service as its platform as opposed to the hardware that previously defined its outlook.

The firm is also looking to make a - gag - 'Netflix-for-games' service in its Project xCloud streaming platform, which was announced in October 2018 and is set to launch in a beta form this year. 

Streaming services will massively lower the technical and financial barrier to entry, something that Newzoo spoke about at PC Connects London 2019's The PC Revolution track.
