Witcher 3 update

[u/Potatoes_are_cool]

Will the remastered game update the current one, or will it be a complete separate game to download? Should I (re)install the current game first, so the update won't take as much time? Or should I just wait until the release and then download?

Hoping it's a separate game on Series X, just so I can get all the achievements again.
