I think you got it right... but I don't understand why it doesn't have 'enhanced' in the name, like the 722 does...
E* marketing ran out of the stuff they smoke when they name things?

And an unlimited number via the RF (NTSC) output.

Any word on when the 722K will be available?
Yes, I believe Scott himself published that the module would be about $29. The 722K is shipped WITHOUT any OTA functionality. In fact, there is no place to connect your antenna. If you want OTA functionality, then the OTA module must be purchased. Please see Scott's sticky entitled "722K OTA tuner up-close" for a demo.
The 722 has only 1 OTA tuner. The two major advantages of the 722K are that TV2 can view the OTA in Dual Mode, and the separately sold OTA module allows for 2 different OTA channels to be recorded at the same time (even though there is only one input, it serves 2 OTA tuners inside). This means (and has been confirmed by Dish/Scott) one can have as many as 2 satellite channels and 2 OTA channels all recording at the same time, for a grand total of 4 different channels recording all at once.
These features on the 722K are very important to some people as Dish does not have HD LIL in fair number of DMA's. Also some people really do need the 2 OTA's even with HD LIL, and some do have a need for the TV2 to tune to OTA in Dual Mode.
So, if you don't need the particular extras of the 722K, then the 722 will suffice, as it does for many. As for me: I was going to get a 722K because I do need the extra OTA, but I've decided to wait for the Dish 922 DuoDVR Sling Loaded (did I get the long name right?). It'll be about a $200 upgrade, but I think the upgrade makes it less expensive than purchasing a new 722K.
