Do you expect something for the 20th anniversary?

If my expectations were high, which they really aren't, this is what I would hope for/expect:

20 new game play elements (implemented into base game)
20 new build mode items (implemented into base game)
20 new create a sim items (implemented into base game)

I 100% don't expect this to happen, but I would like for this to happen. Or at least some kind of limited time event, like the sugar skull and Easter egg event.
