I'm a little surprised Mike Brown is building a new 24-inch telescope
at Palomar instead of adapting the existing one at Mt. Wilson. Or is
that gone as well?

The 24-inch at Mt. Wilson is in use by the Telescopes in Education (TIE)
program (http://tie.jpl.nasa.gov/tie/index.html). It was returned to
Mount Wilson from storage at Palomar (it's a Caltech instrument; Mt.
Wilson is not affiliated with Caltech) where it went after finishing its
stint at White Mountain years ago.
