The Verge is now reporting that the unlocked and unbranded version of the new Moto X will be called the "Pure Edition". It's easy to make the assumption from there that Motorola is making a sly comment on the carrier branded models. If the unlocked and unbranded version is "Pure", it implies that the carrier models have been tarnished with bloat apps and delays for software updates.
We do know that the unlocked Moto X (2014) will cost $499, but we don't yet know when to expect the phone to be available for purchase. Motorola hasn't given a specific release date for the phone, just that it would be coming out "later in September"; so, it is likely to be sometime in the next couple of weeks.
