Here's a quick rundown of the latest Wii info from IGN's most recent podcast:
At Leipzig we’ll see games from ‘another system’ shifting to the Wii. 6-8 THQ games are in development for the Wii (and possibly all for launch). Next week THQ is having a Wii-only Event that will show off games like Spongebob. IGN confirms that a Star Wars lightsaber game is in fact in development. Metroid Prime 3 might be delayed and may not ready for launch day (could just be for the launch window). According to IGN it looks like there will be no Dragon Quest at launch. Also IGN confirms that Excite Truck is a launch game.
