Do owners of original games get upgrade to remaster for free or not?

I own like 3 or 4 copies of the original game with Lord of Destruction expansion. This is what just over on Ubisoft they did the same thing with the Anno series games. They remaster the 1st 4 games so now you can play them on windows 10 and in HD /4K. We had to pay for them and we all own the games.

What I have seen so far. If it is true and they made the game a lot better. I’ll be buying it and dropping D3. We will be back playing a real RPG. Plus not the contest to be the Leader-board King that we are playing now.
