Rittenhouse is indeed taking over the license...BUT they may not do "Marvel Masterpieces". I know for a fact that Rittenhouse will be releasing an "X-Men Archives" set soon (confirmed by more than one artist)...so I don't know if they are just going to release sets such as these or at some point do an all-encompassing all-Marvel set like Masterpieces
either way, they will do a much better job than UD...
