Microsoft pledges to be the flagwaver for its 'remote control' app.
SmartGlass was announced recently at E3. It's the latest attempt by a giant hardware maker to turn the smartphone or tablet into a kind of remote control for the big TV screen.
The SmartGlass app automatically recognises the game being played on the Xbox and then displays corresponding data.
It means users can watch a movie on a tablet and then resume from the same point on Xbox 360. It's also a 'companion app' so users can get useful information about the film.
Similar functionality will also be added to games, so players will be able to direct footballers in Madden for example, or manage multiplayer invites in games like Halo 4.
Now, Microsoft's Phil Spencer has suggested to Joystiq that all first-party Xbox 360 titles released after this autumn will feature support for SmartGlass.
"Expect SmartGlass support in every Microsoft Studios game going forward," he said.
