That would the price up the box and make deployment troublesome for end users. Anyone with a TiVo (I have two) can attest to the nightmare cablecards are.It is much simpler for Apple to simply app up a new 4th generation Apple TV with MSO supported apps for which MSOs get in-app subscription revenues for.I just don't see Apple making a "real" cable box. Apple TV is inches away from running everything in the app store and if they can get TV on there, they'd sell a zillion.

Some are, some aren't...depends on the market segment.
