Well, it will be sad if it all comes down to politics, but it's probably inevitable that it will.
I would be surprised if it was quite as cut-and-dried as Ian points out. The Brazilians want to call the shots here on who does what, and I believe they have been looking into putting together funding to build the course so that they can have more say in who does what, unless that effort has failed. By the same token, I think that most international developers would be pretty crazy to put together a 25-year package to build and operate the place, because they can't possibly have much idea of how golf will take hold in Brazil going forward. It's highly, highly speculative, so nobody's going to bid too high for the privilege, and that ought to keep any local developer's bid under consideration.
My wife did tell me I could do that one for free if I wanted, but I don't know if I'll even get the chance to make the offer.
