I was thinking just now about how Kathy said during the promo tour for TRoS that they weren’t sure where they were going next and that one of the questions they were asking themselves was “Do we go to a new Galaxy?” And honestly, that’s something I could see Rian wanting to do, especially since he even said he wanted his trilogy to be set “in a new corner of the Star Wars universe.” I even think a title like Star Wars: A New Galaxy would have a nice ring to it.

As far as release date goes; my theory is that Disney is waiting to see what happens with Avatar 2&3 before green lighting 4&5. If 2&3 fail, then Rian can swoop in and take up the spots that 4&5 were supposed to have (Xmas 2026 and Xmas 2028).
