I will go absolutely mental if they don't give us world builder.. what BS is that to say its too advanced for us to use??!? Its never stopped anyone from trying........hellodean
i seem to remember a few months ago they said a world builder is (currently) too complicated for us to use, but it isnt yet decided what will happen.
and there is a year or so until its released so its still possible for it to come out. even if its not shipped with the game it could be added later.
as for the make it the same but new graphics, sorry to disappoint you but it wont happen. the new game is in development. your best bet is the modding community to extend it.
