I'm up for any new TS series, but, I would feel incomplete. I would rather give lots of enhancement or features to TS4 first, before moving on to a new TS, until the developers feel that, it is time to move on to a new game which is way better and replaceable (which means, there is no regret for players to transition from TS4 to TS5. It will be selfish to leave the TS4 in the current states, without leaving the players a sense of satisfaction, albeit it is very subjective. It's totally fine working on the timeline for the new game, because I'm pretty sure it takes lots of time & careful planning, but it should not make the player feel the need to not enjoying the current game, just because we're expecting something new in the future.
