I'm feeling pretty giddy. I plan on using my old books extensively anyway (I play so much D&D that I feel like I've already gotten my money's worth out of them, and I still have three campaigns to play in before May). They'll still be fun for fluff, and I have the great good fortune to not own any that weren't at least cool. (Weapons of Legacy was a little wasteful, and I didn't get as much use out of Heroes of Horror as I'd like, but everything else was superb.)
It was a good edition. I'm ready for a new one, though.
I liked Saga and ToB a lot, so that's a plus. Here's to hoping they ditch Gnomes, Half-Elves, and Half-Orcs.
