There's a misconception that they're Dark Sun-specific. Not so. So while they were made popular in Dark Sun, they actually originated in the Forgotten Realms.
They originated in the Monster Cards supplement for AD&D (1st edition), and had no association with the as-yet unpublished Forgotten Realms.
As for Dragonlance, as someone who has no stake in it and is not a fan, it sure does sound like the evidence is showing it will be the next setting. Any concerns over it not "fitting" are pointless, since WotC will just manipulate events in Krynn to accommodate the 4E baseline, as they did with FR. It's not like Krynn has a shortage of cataclysmic world changes in it's history.
