I have to agree, that the current UI on the Hopper is getting old now. I was looking at mine the other night and I was thinking about it and was saying yeah it looks nice but it looks out of date now. So I am looking forward to the carbon interface.
As far as a new Hopper goes, if I were a betting man I would expect to see a new Hopper at CES. While I have not heard anything I would expect it to be a Super Hopper. With built in 4K Support, MORE Tuners, a larger hard drive (Maybe 3 or 4 TB) a unit that can take DISH through the next 10 years without an issue. Of course I do not expect the Super Hopper to be for everyone at launch. I am sure there will be requirements for people to upgrade to one. But as 4K TV become more common I see more people getting one.
DISH luckily has always been known to be on the bleeding edge and really the only upgrade I can see coming within 10 years is a final speck on MPEG 5. Some consider HEVC to be MPEG 5 but I am told its not, its just an early spec version. So we will see where that going. But again I would expect to see a new Hopper at CES. (And of course SatelliteGuys will be there to show you first.
