Hopefully it should be done by the 18th.
This is what I understand and this info is from coming from a few different people on the matter.
One of the big things that was holding the release of the H3 back was Netflix. While everyone knows that there were some bugs in the H3 they felt it was stable enough to release but were waiting on Netflix for the release. Once they found out that Netflix would not be ready for the release they released it the H3 by removing Netflix and gave the date that was given by Netflix for when Netflix would be ready so that was the date on the screen.
So Netflix in order to meet that date sent a version they certified for HD just to get Netflix on the box by the date they told DISH. So U303 was released to some folks and was supposed to be rolled out to all by Friday, however after it was released many people noticed 4K support was missing and contacted both Netflix and DISH about the omission. Netflix reps told those who inquired and said that the Hopper 3 was not 4K compatible. What Netflix was telling people is technically correct when looking at their list of compatible 4K devices, but is also wrong as well because once Netflix finishes their certification process it will be listed as 4K Compatible.
Because so many people contacted them (and DISH) the issue was escalated to both companies, so much so that DISH pulled the software roll out and felt it was best to hold back and that's why most folks still see a message say that its coming. Now DISH is just waiting for Netflix to do their thing. Will Netflix meet the announced date? That's anyone's guess. But I do know DISH did not want to put "COMING SOON" as they know they would be eaten alive here because coming soon sometimes never comes fast enough with DISH.
So I guess the ball is in Netflix's court now to release to DISH a version of the Netflix app which is certified for HD and 4K. Once DISH has that, then we will have that.
Again this is what I have pieced together talking from a few different people so hopefully what I am saying here in technically correct.
I for one am looking forward to having 4K through the Netflix app on my Hopper 3.
