Would be nice, but marketing totally runs Apple now. Unfortunately, Apple kind of cause this problem and have trained customers to expect "New" everything (version, models etc.) at least once a year. Good and bad, but in the case of OS's not so good. Stats show people tend to buy when there is something "New", just like if you put "Sale" on a tag or window.
I actually liked OS X Lion and ran good for me (still use it). I am hoping that Apple instead decides to not put out a new OS for this year and just extend El Cap for another year and to make it solid. Still half baked.
OS X Mountain Lion probably should have been Mavericks...but they ran out of cats for the future and looked like they wanted to implement changes, including personal etc. at the time.
