Yup, San Antonio is a big FIOS area, I believe, where they get a lot of the speed increases first. It also appears to be big in Dallas, of course, but also pops up in a few other locations like Houston and Austin.
Huh! Further investigation seems to indicate that you can get Verizon FIOS, in some of the Houston suburbs, but not anywhere near me, which is purely an AT&T / Comcast universe.
And, for the Tivo/DirecTV box, I'll believe it when it's real. The big question is whether it will have feature parity with standard series-3 Tivos, or whether they'll nuke extraction or Netflix or whatever else.
