The carrier pushes the updates a few at a time in each area, so they don't overload the data system. Eventually everyone who hasn't frozen his updater gets the update. (I'd rather wait and see how badly KK destroys phones before I let it near mine. The S3 4.3 update debacle was only a month or two ago. Has everyone forgotten? I may only be running 4.3, but I'm running it, not waiting for a fix so my phone works again. It seems as if phone manufacturers are learning from Microsoft - version x.0 is a bug, to be alpha tested by the customers. No thanks.)
