Microsoft's "Smart Glass" project is indeed a real thing, and with it you'll be able to access additional Xbox 360 content with "any" device, including iPad and iPhone.
At its E3 briefing in Los Angeles this morning, Microsoft showed off how Smart Glass will let users interact with Xbox movies and music with tablets and phones, but more interestingly, it unveiled how games will use the technology moving forward. In EA Sports' Madden 13, for example, players will be able to pick plays, create plays, and fiddle with rosters on their tablets or phones while simultaneously playing the actual game on their big-screen TV.
In Halo 4, users will be able to access extremely detailed gun data as well as join multiplayer matches via Smart Glass. It looks like these features will specifically be delivered via Halo Waypoint, Microsoft's hub for all things Halo.
Microsoft didn't address how exactly Xbox Smart Glass will be delivered, leaving questions about price or distribution up in the air. Last week's rumor noted that Smart Glass will have an official app across every store, including the App Store.
Xbox Smart Glass is expected to hit later this fall. An Xbox Live gold subscription will be required for "some" of the games that will support it.
