According to throwaway11113454, a Reddit user, who, presumably know some artist from Rockstar, the studio is preparing a great storyline DLC for Red Dead Redemption 2
In addition, we will again play for Arthur Morgan, and the plot will focus on the aliens, whom we have already seen in the game as Easter Eggs. DLC is scheduled to be released in December 2019 / January 2020.
That rumor also contains some info about Red Dead Redemption, which will include all the new gameplay and graphics mechanics of Red Dead Redemption 2. A remake will also have new dialogs related to the 2018 prequel.
