Only and educated guess, but on October 8 Obama signed into law new FCC requirements for closed captioning and other handicap assists. Among those, a requirement that all new devices with EPGs in them have "audible" EPGs. All suppliers have a year to comply. Could that be a feature uploaded to existing boxes? Maybe. My best guess would be that this is doubtful. I guess there could also be loopholes or waivers, but right now from where I sit it looks like new models on the horizon. I imagine that this would not affect existing boxes or replacement of existing boxes, just new boxes. But who knows? I am only guessing.
