But maybe for a preview look at COBOL, there is huge demand for experience people.

Is there? I actually looked into this once, and nearly all the Cobol work I saw mentioned was being outsourced to software consulting companies in India. And it didn't sound like an especially good job there, either.

If anyone is genuinely paying disgusting amounts of money for deep Cobol expertise, I'd love to see any public evidence that this is happening on any significant scale!
