I'm using TiVo for OTA/Antenna and am trying to upgrade from my TiVo Bolt (for cable and antenna) to an Edge, in part because I'm getting pixilation on some channels on the Bolt. I purchased an Edge for Antenna and am glad to see signal strengths improved to 86 from 65-72 and pixilation does not occur. However, I don't like only having 2 tuners, limiting me to recording one show while watching another or recording two and watching nothing live. I know TiVo HAD an Edge for Antenna with a 2 TB drive and 4 tuners. Does anyone know if this product is coming back?
