So I read Final Crisis at least once a year. I love it, obviously. I've also gotten more interested in the Fourth World and the New Gods mythology as a whole thanks to Tom King's work on the current Mister Miracle. Now, the Fifth World was supposed to be the next evolution of the Gods of New Genesis and Apokolips. At the end of Final Crisis, the New Gods were reborn on Earth 51 and in Multiversity we were told that different emanations of the New Gods exist throughout the Multiverse, while the true forms of the New Gods reside in the idea/conceptual space of the God Sphere. (which means even the classic forms of the New Gods on Earth 51 are still projections from an even more abstract form, similar to the true form of Darkseid as seen in Final Crisis and Seven Soldiers). So while the New Gods exist in the God Sphere and cast reflections of themselves throughout the Multiverse, does this still mean that they could somehow continue to evolve into Fifth World Forms that exist beside all the capes and mortals?
Ultimately, through this winded post, my question is still: Does anyone think DC comics or Grant Morrison will ever delve into this story of the Fifth World in the future?
