I have a 921 and a 6000, both of which would supposedly be upgraded to MPEG-4 receivers when the time comes. My biggest fear is that the new receivers won't have OTA capability - why would they if E* is trying to market LIL HD? If that is the case, I'll have to decide whether to (1) Upgrade to MPEG-4 and buy stand-alone OTA tuners, (2) Upgrade to MPEG-4 at full price and keep my 6000 and 921 for OTA, or (3) Choose another provider. At any rate, these old receivers won't be "boat anchors" anytime soon, as they will certainly be fine for OTA, SD, and whatever HD channels we already have for a (relatively) long time.
