Just wondering if players will be restricted, (not that it's really a "restriction") to the core classes, or allowed to also choose from the official archetypes for each class.
The Magus class, for example, has the following archetypes available (above and beyond the base class):
Bladebound, Hexcrafter, Spellblade, and Staff Magus from Ultimate Magic (the same book that the base Magus class appears in)
Kensai, Myrmidarch, Skirnir, and Soul Forger from Ultimate Combat
