Trying to make sense of the month-and-a-half delay between the release of Nintendo's MotionPlus and the first Nintendo game to use it, Wii Sports Resort, GameDaily proposed a theory. Maybe there would be games to play at launch -- old games! "With a nearly two-month span of time between the accessory release and the game's arrival at retail," GameDaily's Micheal Mullen wrote, "we expect that Nintendo will release patches that will make the new accessory work with your already existing library." The first game to receive such treatment, of course, would be the original Wii Sports.
Nintendo's response to GameDaily suggests that this won't be happening: "The Wii MotionPlus accessory is only for games that are designed to make use of its abilities." Nintendo isn't really much for patching games with updated functionality, unless you consider releasing the game again seven years later on a different disc a kind of "patching."
