I have been a fan of the Horizon franchise since it came prepackaged with my PS4. I would love to see a 2026 release of Horizon 3, but I can understand pushing it to the 10 year anniversary. They have done so well by the previous games, I would rather they take extra time to perfect their vision, than put out a rushed finale.
I am a little leery of the MMO, as I personally am a mostly solo player. I don't like the pressure of other players and the need to group up to take on bosses and instances
