I have a suspicion that there won’t be much to differentiate the 7 and the 8; doubt they’re severely changing the design after having just done so and invalidating the thousands of bands people already own, and there aren’t many huge health features they can add yet. Coveted, societally-changing health features like blood pressure and blood sugar monitoring definitely not dropping anytime soon.
The only real difference between the 6 and 7 was the 7 getting a *slight* redesign with the larger screen and fast charging. I figure the 8 and 9 will keep the same design as the 7 and add maybe one or two features and improvements, and different case colors/materials. Maybe they’ll surprise and make a larger 49mm Watch or something but at the moment there isn’t much they can do.
Better battery, maybe a FaceTime camera? That might just be gimmicky enough to be enough.
