Granted, these are being released in conjunction with Star Wars - The Clone Wars: Republic Heroes, which has no MotionPlus support that we're aware of, but come on! Any lightsaber accessory should have an extra slot for MotionPlus. We don't care if LucasArts ever makes another lightsaber game or not. Hell, we'll pick up Red Steel 2 and just pretend we're using a lightsaber. At least, we would, if these accessories supported MotionPlus.
Oh, the Clone Trooper blaster also comes with stickers.
Update: We've confirmed with BDA that neither Republic Heroes nor its accessories support MotionPlus.
