Apple is probably waiting more for the right time.

Apple would not dare risk taking that kind of hit to there image, just to say they have a LTE capable device.
Something people do not talk about, is developer support for the next generation networks. That has to be in place as well, to create a demand for moving into the 4G arena. That's still underway.
I believe, Apple understands the market better than most. More importantly, they have an ecosystem of products that is unrivaled. For NON Apple manufacturers they HAVE to offer devices early and often to better compete. Apple will release a next generation device at the perfect time, and you can bet it will operate to the expectations of there followers.
