I agree with wanting a preteen stage. I always thought of the adult stage as the middle age stage. I like that they came up with some new body details for elders, but it's a bit dramatic, in my opinion. Of course, what isn't dramatic about the Sims?
Regarding the end of Sims 4, what I read and understood from the newsletters was that there will not be any more new Sims base games, ie. Sims 5. They plan to continue with the Sims 4, but it will be mostly focused on improvements and occasional upgrades to game play. I would personally enjoy a more refined game. I'm also not opposed to getting a better gaming system to accommodate future improvements and dlc. I would love it if they did a revamp on Neighborhood stories and gave more autonomy to the NPCs. I hate having to use mods to get that.
