Microsoft chief Steve Ballmer gave clues at his presentation for the Japan Microsoft Developer Forum (video below) that the upcoming Mango update for Windows Phone 7 would not just have a large number of features but might be matched by new hardware at the same time. The release would have over 500 new features, including the known expanded language update that would give Japan devices by the end of the year. He alluded also to more details of hardware partners and carriers, suggesting more hardware might show at the planned May 24 event.
