The Olympic commentators were only under contract for the Olympics so they are not required to bring them back.
There's actually no reason they couldn't get Tracy under a contract again as a freelancer leaving her available for worlds as well.
I can't imagine Skate Canada would have gone for this team if live feeds weren't going to be an option. There are 3 networks available to get it out there.
This is probably not nearly as bad as some are making it out to be.
