First let me say congratulations,

Second, if they have not signed you to the gig you should not be talking about who your going to be working for publicly unless they you have been given permission, if Paizo hires you they will want to put you under a Non-Disclosure Agreement.

The most I would ever say publicly is that as a major publisher has become interested in you because of your knowledge of the specific genre of setting material they want you to work with.

Again congratulations.

That's just my two cents.
