One concern that I don't see on the list: the main problem with 3E is that characters start too powerful and gain additional power exponentially. My only concern, now that I've had a chance to digest the news, is that this problem seems to have been further exacerbated. I'm disturbed by the main complaints which seem to be that classes haven't been souped-up even more; if there's anything 3.5E is missing, it's that classes need to be souped-down.
