I think we can expect Dragonlance, Forgotten Realms and Spelljammer. Everything else is cake.
However, I'd really love to see Greyhawk and Mystara have something done for them the most. The other campaign worlds, I wouldn't say no to either, but don't expect we'll see them. I think the most troublesome would be Al-Qadim, Maztica, Horde and Kara-Tur as they attempted to hew too closely to real-world locations, if not the "fantasy earth" historical settings they put out in the green books back in 2E.
