Moving Columbus west kills them since they're in the eastern time zone and getting more popular with people being able to watch at normal times. Detroit got promised to move east so they aren't going back.
Only hope for QC is probably the Coyotes or the Vegas team being a quick disaster like Atlanta became in the last few years
Detroit is in the eastern time zone as well. Both they and Columbus wanted to be eastern conference teams because being in the eastern time zone but playing in the west meant that a large chunk of their road games were being played well after the traditional 7/730 start times, rather than the 5 or 6 teams like NJ have to deal with.
