Microsoft is preparing to make some kind of announcement about Original Xbox backwards compatibility support on Xbox One, it seems.

The announcement will be made during the next episode of Inside Xbox, which premieres on Tuesday, April 10, at 3:30 PM PT / 6:30 PM ET.

"One of our most common requests is for Original Xbox Backward Compatibility news, and we'll be starting off the show with a big update on just that," Microsoft said in a post on the Xbox Wire.
