Do you still have inside info on that (like before 3e's release when you were a playtester), or are you just guessing? Because from the looks of it, I would guess that a closer analogy to the Complete Warrior would be Player's Option: Combat & Tactics.A'koss said:The Complete X books are essentially Splatbooks +. The Complete Warrior will contain updated PrCs from Sword and Fist, a few new classes, feats, a few spells, equipment, new combat tactics and so on. There will be a fair bit of carryover from S&F.
That still paves the way for a spellcaster book later on though. I just hope they won't remake Skills & Powers.
