TS4 hints at "unexpected" expansion packs coming in 2020

"We're finally at that place where I'm not convinced they can guess our next couple of packs anymore." well, we should... I'm still heavily expecting Hobbies, Generations, Farming, etc... They keep talking like they had a list of things that they need to add checkmarks to little boxes, and that they filled that list, but come on... There's a lot of other packs we still want and need.
