New boat for Craig McCaw?

I was talking with a friend today who works for Craig McCaw...in fact, he installed the phone system on Tatoosh when she was built. He mentioned that Craig is looking into building a new yacht, something in the 420 to 480 foot range. I think right now it's in the planning stages, but it may well come to pass. Do any insiders have any more detailed knowledge of this? I'll see if my friend can keep me up to date as he learns things.
