Hints for future sims 4 packs in sims freeplay?

I think it's probably easy to just port stuff from one game to another. I imagine it's easy to just add objects, but the gameplay is different from one game to the other, so they can't port everything. And beside that, they probably also have different long term visions and plans that are somewhat different. I saw they added some pretty peackok feathers in a vase in Freeplay I think, would be nice to have those in TS4 instead of the pampas grass and steel ones they gave recently.
