On Wednesday we learned a lot about the Xbox One, the Microsoft next-gen gaming console, but there are some questions that remain unanswered, so I sat down with Yusuf Mehdi, Corporate Vice President of Marketing and Strategy, Interactive Entertainment Business, to try to get to the bottom of a few lingering questions and a few of my own. All of the demos we saw at the Xbox campus have been on gorgeous flat panel HDTVs running at 1080p, the highest of hi-def resolutions. In the near future, though, Ultra-hi-def TVs (UHDTVs) are expected to become as common as HDTVs are today. Will the next-gen Xbox work with these next-gen TVs? “The video and interface portions, absolutely. Games developed for 1080p will run at 1080p, obviously.” It will support up to 4K at launch for things like Blu-Ray, but what about later? “There’s no hardware restriction there at all.”
