There’s going to be a lot of disappointment if the S9 is incremental!I’m wondering if the S9 will be relatively incremental as well. Then S10 will bring a new chip and battery life, so the Ultra 2 also benefits. I can’t see them wanting to close the battery life gap between the two watches as it takes away from one of the Ultra’s advantages.
(This is based off the idea the Ultra is a two year device)
The series Apple Watch being a yearly device feels like a problem for Apple now. Looking at the 5/6/7/8 there just aren’t enough new features for a splashy annual upgrade. Maybe both the series and Ultra watch will go onto an intermittent schedule like the iPads and be updated when it makes sense?
