I do believe we will lose some editors but some will stay to see what UPC finished product is or leave and come back after it is supposedly finished.

IMO, either UPC will be fixed and upgraded enough that some will come back or stay and/or it will bring a new/different generation of editors who never knew what Legacy was like so won't complain.

Will Fandom do better or worse is something we will just have to wait and see.
