Microsoft has long spoken of its ten-year plan for Xbox 360, but that doesn't rule out a successor launching during the period, according to European Xbox boss Chris Lewis.
"We think we're a little over halfway with the life cycle of the console, but that's not to say there won't be an overlap," he told Metro. Xbox 360 launched in November 2005.
"I'm not going to announce specifically or talk about timing," he added. "But you could imagine there could be overlap, it depends. We're not being specific about the next generation at this stage. We're very fixated on what we're doing right now and the success we're enjoying."
