There has been evidence of this new remastered original trilogy slowly building online over recent months. This is due to the restoration company posting short clips to a quiet unknown YouTube account.
Check out this video on an explanation on what has been happening and a comparison between the new remaster and the current 4K discs.

Can they make money on it? There’s your answer.
Not really. Disney doesn’t really release many titles on physical media anymore and were one of the first companies to stop doing so (as compared to Warner Bros., which regularly puts out catalog releases). Lately Disney has released only the biggest brands, Marvel, Star Wars, and Pixar, often in the form of a handful of very expensive SteelBook 4K releases in the case of their TV shows. So they are not automatically predisposed to release on physical media.
Second, it’s been nearly 30 years since the Star Wars Special Edition was released in theaters and nearly 15 since Disney bought Lucasfilm. Disney could’ve made plenty of money selling the original unaltered trilogy in that time, especially earlier on when physical media was a bigger market. But George Lucas has made it clear that he never wants the original versions released, and at least thus far Disney has honored that.
