I imagine they plan to allow customers to have two of these in their home as an option to just a 622 or 722. With the x22's, you only have one HD setup and the second output is SD. So, if you have two HDTVs you have to get a 722/211 or similar setup, which leaves people with a second HD that doesn't have DVR. That sucks for some people who have an HDTV in their living room and in their master bedroom. Those customers have to either give up HD in one of those rooms or get a 211 and have no DVR.
Hopefully, DISH will allow the promotion to include a 622/612 as a valid configuration. Then we can put the 612 in the living room and the 622 in the master and backfeed to little Johnny's room. Maybe put a 311 or 211 in another room. Easy to do with a 1k2.
Also, will be a neater install if DISH is smart enough to put the DP Separator inside the box this time. Then it could be one cable in from dish, one HDMI out to TV. Wouldn't that be sweet?
