I'd be happy with themed monster tomes. Given the annual story thing they've got going on, that could well be on the cards.I hope they never do a Monster Manual 2. I would much prefer thematic monsterbooks, like Fiend Folio, Book of Fey, Tome of the Dead, etc. That would make the Monster Manual all the more special. I also really hope they avoid a Player's Handbook 2 and instead release splats as thematic supplements as well.
Given the OSR-love that's gone into 5E, I agree, the second monster book should be the Fiend Folio, while the third is "Monster Manual II."
