OK, having played a few more games of Civ Rev, I'm gonna go out on a limb and say that there are at least even odds that the next iteration of the core Civ game does away with worker units. I've always hated micromanaging them, automating them is a crapshoot (besides which, if you have to automate some feature of your game, it isn't a fun feature worth keeping), and the Civ IV design team has publicly stated that they were more than happy to get rid of late game pollution whack-a-mole. I wouldn't mind seeing something like Rev's model, where certain buildings improve all terrain of a certain type inside the city radius (i.e. building a Granary is like putting farms on all the plains in your city's radius, building a Workshop is like putting mines on all the hills in your city's radius, etc.), make it into the core game.
