I think AT&T is largely done with their big fiber push. Over the last few years a LOT of homes that had been on Uverse or slow DSL got upgraded to AT&T Fiber. Sounds like they'll very selectively continue to expand fiber now but if they haven't converted your address yet, I wouldn't hold my breath. Maybe AT&T is trying to decide if they'll go with some form of wireless connection for future home broadband expansion, as Verizon and T-Mobile are doing. I've even read that Charter is considering using some form of fixed wireless to expand at the edges of their footprint.
