The Sims 4 Seasons

It appears they have already been dropping hints about Seasons the same way they did with Cats & Dogs, probably for 2018, next expansion pack. In the 8/22/17 patch update, they started with, "The end of summer is here and… you know, whenever I talk to my mom she wants to talk about the weather". People have speculated in the first Cats & Dogs trailer about weather because the cat's thought bubble had weather (rain maybe?), in it. They also had a dog and child on the beach playing in a puddle of water. After the Sept. 12 patch update, many were talking about finding puddles everywhere. My sim autonomously started mopping up various puddles in the yard in my new save game. Where did all those puddles come from? There was absolutely no reason for them and are not usual in Newcrest. I figured they might be pet pee puddles because we already knew about pets by then. However, we did find out about about cats and dogs earlier than usual from Simmers finding icons and code for it in the game files. Apparently they have already found icons for Seasons (after the August patch) but I haven't seen any code reported yet.

You can bet the Simmers will be scouring the game files for code in all coming patch updates and packs (especially in the Cats & Dogs expansion pack when it drops). Code will pretty much confirm it's coming next.
