My group was quite happy with Complete Warrior, and I hope that it's a template for future books from this point. The original class books were fine for their time, back when 3e was new, but each one suffers from various problems, and only two are reasonably balanced (and only one is actually interesting to read). It sometimes took months or more to identify the problems within them, but CW cherry-picks some of the best material from them. Presumably, the other books will do the same. I see the Complete series as more of a 'lessons learned' version of the class books.
One a completely unrelated note: Alan, where's the link to your rogue gallery for your Drow game? I was looking for it the other day, and couldn't find it.
