Yes, but based on last year's Air release, the LTE models weren't available for a week or two. They slowly trickled in, a few at a time. The good news this year is the Apple SIM. That means one model. I can't tell you how many trips I took to Best Buy searching for a Verizon Air, only to be told they had AT&T that day. The next would be T-mobile. Tiresome!
They'll get the LTE models, but they'll get wifi first.
