I wasn't going to post in this thread, but after seeing the comment regarding KR going down the power rangers route, I thought that I shoud state that I have heard the first 5 episodes were re-written for a younger audience. This comment came from Nathan Long's blog.
As for the recasts, I really don't have too much to further say than what Keith as already said... or hasn't said, depending on your perspective. IF these are the new cast members, it looks like 2 of them have a background in singing. Interesting.
