A quick cut/Paste from my "To Buy" list:
Currently Available, but still unsure:
Dawnforge
Lone Wolf
Dawning Star
Hero System, 5th
GURPS IV, Book1
GURPS IV, Book 2
Immediate buy once released:
Shadowrun IV
Spycraft II
Weapons of Legacy
Book of Aspects (Fireborn)
Iron Heroes
And, of course the minis:
Angelfire
With the exception of the few books at the top of the list, which I haven't bought because I just discovered how cool they are/might be, I have everything currently out that interests me (at least in print, I just started buying some of the excellent PDFs out there), so most of my "must haves" aren't available yet.
