It's kind of funny that Miller seems to be doing Crisis on Infinite Earths since they basically adapted "Final Crisis" (or at least parts of it) on the final season.
Sort of makes you wonder if a return of Doomsday isn't too far behind, or if that would be part of the 'Crisis'. The big question would be if Miller would do a return bout between Supes and Doomsday in the same way as the original DC storyline.
