UverseTV will be gone within 2 years max. It is being phased out. They are merging direct with Uverse to have a single TV service. Not sure what the actual name will be, but last I heard, it was "ATT TV". Kind of lame, but yeah.
I install 54s all day and NEVER install a RB unless there is a 61k on the W/O, then it actually calls for a RB. It's a huge waste of $$ (in AT&Ts eyes) to install them on non 4k jobs, when 95% of the time the customer doesn't even know what an HDMI cord is.
