It looks like GameFly was right once again.
We recently reported that the renter/retailer put up a listing for Tornado, which was assumed to be a localized version of the Japanese game sharing the same name. Now according to a blurb in most recent issue of Nintendo Power, the Katamari-like game is indeed confirmed to pop up in North America, although no timeline details were given.
Nintendo Power also reveals that Tornado will include some microphone blowing elements, which worries us a little bit. As long as the game doesn't overdo it, though, we can't help but think that this will be a nice addition to the DS library.
