If ya ain't figured out that LTE is the only future att will offer, then you may be the one I am looking for to sell this bridge I have. You can stay were you are, move to another provider or move to att LTE and like it. Start figuring out where you want to go... T will play a big song and dance about their 2nd wind at build out, but anyone that believes them is a fool. Once they get out from under "provider of last resort" rules, watch out. I would bet that areas will start to go dark when that happens.
They won't get rid of DSL, but it's not like they're investing anything in it either, other than IP-DSLAMs, which are largely just to reduce cost, and push the slow speeds out a tiny bit farther.
