Agreed, if they refit or replace the enterprise so quickly it simply just confuses everyone and takes away how significant the Enterprise is in the new franchise.
But new Toys are cool. Kids want to see the New Batmobile or the new Optimus Prime.
A boob job reversal on those nacelles would be nice.
Stuff what kids want, this is about what I want.
Enterprise stays as is getting into adventures for atleast 2 decades, only until then she may finally retire.
