While it's not clear from the statement exactly what it would mean for the system to "go" for that long (is that when systems will stop rolling off production lines? When games stop being made? When Xbox Live shuts off for the old system?), Mehdi said that Microsoft plans to fully support the Xbox 360 for the time being.
"We're going to continue to invest in the Xbox 360 and the two devices can work in concert," Mehdi said later. "It's not like the day we ship the Xbox One your 360 won't work; we'll continue to support it. In fact, we're going to ship over 100 new games on Xbox 360. So you'll still be able to play your [older] games, just not on the same exact box."
