I like Complete Expert, for what it's worth.
But I'm more interested in seeing what they actually put in the 'Skilled' book. Of course there will be some Bas Classes and PrC's, a selection a feats, a few new spells, but what else? Complete Warrior had alot of info on the "Martial" campaign, and ways to change warrior-related stuff (which weapons are simple/martial/exotic, Dieties, etc.) What will the skilled book have? Perhaps skill and feat based magic? Advice on a "Skill-Based" campiagn seems very vague, what other campiagn type info would they include?
