The fact that the actors would be younger is really the only thing it has going for it. But I think it will be interesting to see them older, and it may work better for 'passing the torch' (whether or not are new characters will be decent is another matter - who knows at this point).
So, unless it was an alternate timeline where Lucas sold it two plus decades earlier, or somehow magically had it stripped from him by force (I like the sound of this timeline), I think we're better off.
