In summary then: "Oh no."
Batman comics were never written by Bob Kane. Bill Finger was the original writer, and while other folks eventually shared the writing chores, it's still universally agreed that Finger was the best writer of Golden/Silver age Batman. So if you're reviving a property, it would be foolish to not hire the equivalent of Bill Finger if he's still around. In this case, Batman Beyond succeeded because of Bruce Timm, Paul Dini, Alan Burnett, and Glen Murakami. It would nice if at least one of them was involved in this project--if it is more than a rumor. If so, I hope those ugly designs are fake.As an example, the generation that grew up watching Beyond and are now working at Warner Animation may have a valid story to tell. Batman Beyond can only continue if others tell their own interpretations of it. Batman comics eventually were written by someone other than Bob Kane.
