Was it any surprise that Verizon would release their variant a week after everyone else? This is good for Big Red since we are used to a much longer waiting period from them. This week should give them the time they need to add some bloatware and get it running nice and snappy on their network.
AT&T will be releasing the long awaited MotoX on August 23rd along side Sprint while Verizon will release on August 29th. These dates are still not solid so take them with a grain of salt.
