As for everything being erased, notice how Prime always breaks the rules, even comic book logic. There's no reason for him not to show back up. I mean even if it was erased and he ended up back on Earth Prime with no memory, all it will take is for him to flip through the pages of Infinite Crisis, Sinestro Corps War, Legion of 3 Worlds etc. And it will all come back to him.
