No, the lead time for the design of new iPhone models is over a year. It has been the case for a number of years now that the first details already leak before the preceding model has launched.

I’ve lost track of what the latest model is, the upgrades are so minute and forgettable now. Are they just going to keep releasing new models every year? Are we going to reach iPhone 50 by the time I die?

I can’t see xitter because they say so, but this is likely speculation on next-next-gen 17 as next-gen 16 is about to be released.
