Pathfinder RPG Final Product Goals

It might help focus the discussions here at the boards if we knew more of the project goals are for Pathfinder RPG. If anyone has questions or answers to share, please post them here. Knowing the questions that players have can be just as important for the game designers as having the answers to those questions, especially in foreseeing future developments.

Here's a few questions to begin with.

How many pages will the final product contain?
Will prestige classes be included in the final product?
Will more base classes beyond those in the classic 11 of 3.5 edition be included?
Will there be further supplement books, such as a Pathfinder Rules Book 2 if Pathfinder RPG is successful?

Based on what has already been stated:

Will more base classes beyond those in the classic 11 of 3.5 edition be included?

No.

Will there be further supplement books, such as a Pathfinder Rules Book 2 if Pathfinder RPG is successful?

I believe someone said a MM-type book is planned.

How many pages will the final product contain?

420 pages (it's listed on the product page).
