...Be prepared for more Dwemer monsters (those ball guys).
Oh yeah, I forgot that they had been confirmed in one of the Game Informer videos...
It wouldn't really make sense to have dwemer ruins without some kind of lore on them. There was Ayleid related lore and quests in Oblivion so I don't see why there shouldn't be Dwemer lore and background given in Skyrim. I would expect some sort of quest to do with them at some point despite them being long extinct.
