New battle pass event

I remember a hint that the Sims might be doing some pack refreshs in the future.  It could be an interesting idea to do a battle pass event leading to the refresh or just following the rerelease.  These battle pass events would only be accessible to those who own the pack during this time and could work almost like early purchase content.   

If there was an Island Living refresh some of the items for instance could be the mural on the wall of the Sulani cave, shell decorations or clutter maybe another an islander tatoo?
