There are always
going to be fans of the prime universe who want it back because they were here first and carried the torch for over 40 years, immersing themselves in various aspects of it, buying merchandise, etc. Quite a few grew up with it.
But I think the majority of people don't care what universe Trek is as long as it entertains them. In that
capacity, they have no more preference to the Abramsverse than they do to the prime universe and would be totally okay if Trek was all rebooted again in several years.
