Stuff that I'm looking forward to (in no particular order):
Nyambe. It's a big chunk of human myth that hasn't been covered in detail yet.
Underworld, 2nd Edition. I followed the design columns for this game on rpg.net pretty closely, back in the day. The setting really interests me, but the system doesn't; since there will be a d20 conversion in the second edition, I might actually get to play it now.
Farscape. I probably won't ever get to play this one, since I'm the only one in my group who watches the show, but I want it anyway.
Pirates and Musketeers from AEG. Swashbuckling is good. Plus, the sample setting will be Theah, which includes faux-Elizabethans and faux-Russians, along with fate magic, shapeshifting, courtly intrigue . . . these are a few of my favorite things.
The Dangerous Land of Zo. Nothing's been heard from New Retro Games in months, so this is probably vaporware. I still want it.
The Epic Level book. Our Greyhawk campaign has been running fior about 15 real-time years, and we're well into Epic levels by now (using FRCS and now Dieties and Demigods rules.) This will make my life soooo much easier.
Stuff that I've playtested for. I'm not as feverish in my anticipation for this stuff, since I already essentially have it, but I look forward to holding the books; in particular I look forward to the Liber Beastarius, the Second World campaign setting, and Oathbound.
