DWTS Pro Watch: Contracts

I know things are heating up with speculation about the pros and who is returning for Season 17. One thing that has raised my eyebrows though was yesterday's news that Kym Johnson wasn't returning. She is reportedly headed to DWTS Australia to work as a judge for the next season, although she has yet to confirm that news. I found the announcement rather curious because of this: Contracts are pretty ironclad and it's hard to get out of a DWTS U.S. contract.  Yes, it's not one big happy family of DWTS shows, it isn't easy to jump from one country's show to another. That's not to say that it hasn't been done before, we know it has. I'm just saying a DWTS U.S. contract is more challenging than others. Is there subtext in this post? Perhaps.
