Hey gang! I recently visited Ryan Drummond's page, and looked under "Current Events" and saw in a recent article, that it's just may be_possible_that Sega will be dropping the 4Kids voice cast and returning the original!
Although he has posted this back in October of '06, and no updates as of yet. It's just a floating rumor, but Ryan himself IS checking it out for himself. So stay tuned...
