Not sure if thats similar to Windows bring re written as a 2014 OS rather than the 2014 version of the 1980's OS. Problem is making a user able to migrate.They can make it look the same as Windows 8/10, but software vendors would need to rewrite and allow current users free or almost free access to the new version. Don't see this happening anytime soon.
Yes and no.
What Apple did starting in the late 1990's was create a new OS from scratch (in the sense of the Darwin abstraction layer painted over a Unix core).
Around 2005-6, seeing the limitations and upcoming demise of the PPC chips, they re-wrote/re-compiled the OS to run on Intel chips, as different proposition than the original move to Unix. I think SJ was suspicious of being able to stay with PPC even from the beginnings of OS X, and they either created the OS in a manner to make the later switch easier, or created both in parallel from the start.
