KW seems like a relatively simple dude. I mean, I know he likes to drive nice cars, etc., but we're not talking about someone who needs to run around the world to the biggest events and venues and make it rain. He's pretty content doing his job and hanging out with his family. At least from what I hear.
You get a few million in the bank - and more money won't mean you can do more of that. You've already got enough to pay for all of the stuff you want to do.
I think he's pretty comfortable and would be surprised if he ended up elsewhere.
