I think you're taking a more BFP approach to perceiving this mod's future, at least from a community standpoint. The BFP community seemed to like having an obscene number of characters to play, despite have any real in-depth gameplay (gauntlet melee anyone?). ESF is currently working on making outstanding gameplay, a task they're doing very well. The next version, I believe, is going to focus on transformations. I think they're trying to build vertically (improving what's already in, adding more features, cleaning code, bettering sounds and sprites) than horizontally (do more of the same with no real improvement).
Besides, King Cold? Jeice had a bigger role in DBZ than King Cold. I'd rather see the Orange Aussie over some oversized pink guy. o_o
