Jim Ward from LucasArts has let the cat out of the bag and revealed that they are indeed working on a Wii lightsaber game. According to him LucasArts has internal prototypes that let them use the Wiimote as a lightsaber saying, "internally we have already played a lightsaber game on the Wii. It’s a lot of fun."
Like I said previously , LucasArts would be monumentally stupid not to take advantage of the Wii in order to give us a Wiimote lightsaber game. I'm glad that they have been listening to the fans and are actively working on the idea. If we don't get an announcement at E3 about this game I would expect one by the holidays. In any event a Wii Star Wars game that uses our Wiimotes as lightsabers is on the way and I couldn't be happier.
