Due to circumstances beyond my control, I may be forced to drop Comcast and sign up with UVerse. We already know that the current HD TiVo boxes don't support UVerse, so that's not the question. And with luck, I may only need to be on UVerse for a short period of time before I can return to the comforting bloop bloop bloop TiVo soundtrack. So here's the Q that's weighing on my mind: what are the chances that the S5 (or whatever they're calling the pending 4/6-tuner units later this year) would support Uverse **and/or** Comcast? What are the downsides I'll find with UVerse, other than not being able to use TiVo? Any upsides?
