1) 27 inch iMac with black bezels and silver or black color. That will be a hot ticket item.
2) AirPods Max 2, with lossless, better ANC and better battery life, throw in a real case but thats not a biggie.
3) New HomePods, either big or small, allow the ability to make them become a surround system
4) Have the Apple Watch go back to stainless steel, titanium in theory sound nice but its prone to nicks and dents, where as the stainless steel can be polished, the titanium cant. Heck throw in a shiny like stainless steel Apple Watch Ultra.
5) Bump up iCloud storage.
6) When the tech is ready, a foldable without a crease
7) Fix the iPad OS
