A blu ray release is also on the cards. Warner have spent quite a lot on the Dallas restoration so they want to recoup some of that cost.
The problem is, that a Bluray release is quite expensive. Each Bluray glasmaster containing 4 or 5 episodes will cost them around a thousand bucks, and you need loads of those glasmasters for the entire show. Those boxes will need to be high prized (around 400 Dollars
at least for 14 whole seasons) and sell quite well to make them any profit, and i quite doubt that. And i also don't see them putting any effort in new extras as well, as that would make it even more expensive.
They didn't even release TNT Dallas properly on Bluray, although the HD material was already available, they just released it on shitty-cheap DVDs in much lower resolution than what was seen on TV, which was a real shame.
Even the worldwide very popular Star Trek TNG was a huge letdown on Bluray for CBS financially, the first 2 or 3 seasons did alright, but then the sales numbers dropped so drastically, that at the end the whole project was a big minus for CBS, so that they didn't even bother to transfer DS9 or Voyager to HD to this day.
As much as i would love a bluray release, i just can't see enough people worldwide buying those in the numbers that are needed to make it profitable for them.
But it's good to hear the remastered seasons will be digitally available for purchase on Amazon, as that's a valid option to kind of "own" them in HD quality.
