The newest issue of CoroCoro is out, and details about Ryusei/Star Force 3 have been revealed according to The Undersquare. According to the Teaser site, a new element of 3 will be "Noise" waves that run about and offer a great deal of power, but run the risk of causing chaos in the Wave World in a similar vein to Dark Chips from the 4th and 5th Battle Network games.
One of the scans seems to back this up, depicting a changed battle screen and a possible wireless connection between Cellphones and the DS.
Unfortunately there are no details on what the cast will be up to or about any potential transformations for MegaMan. You can be assured that we'll keep you posted on any future developments.
