Microsoft has been planning to bring Xbox Live support to mobile devices for some time now, and while job listings have, until now, been the primary indication of this, some harder evidence has been brought to light.
According to a recently uncovered (via Kotaku) internal marketing document, Microsoft has definite plans to deliver its mobile Xbox Live service (or Xbox Live Games as it will be known) to Windows-based phones in the near future. Whether the service will be available on other devices or phones isn’t known, nor is when the service will be made available or what exactly it will end up offering users.
Another unanswered question involves the recently announced Xbox Live Game Room, which lets Xbox Live users play retro titles via an avatar-loving online space. While the full service probably isn’t practical on a mobile-device scale, including emulation support could prove to be a rather compelling feature.
I've contacted Microsoft to find out more about all of this, so stay tuned.
