I don’t think they will remake the existing prequels but I think through their spinoffs they may well make prequel films which could be accepted as replacements by those fans who don’t like the current PT.
Rogue One is a direct prequel to ANH you could even count it as a new Episode III if you like. It covers events mentioned in the open crawl of the first official film made in much the same way that ESB refers to the Death Star being destroyed in ANH.
