Yes, this is very fast and very impressive. Droid-Life has a story on it as well. Looks like Motorola is following through on their promise of fixing the age old update problem. In fact it looks like the Moto X KitKat update will even beat the Nexus 7 LTE 4.4 update. Nothing official on other carriers but if Verizon is already soak testing the others can't be far behind.
