I've put in an order with Amazon... probably my last new purchase for a D&D book... that sort of makes me sad... though I will be picking up peoples used 3.5 books as the switch over to 4E...
"Rules Compendium is aimed at those who want a concise rules reference for 3E. It’s intended for people who might continue a 3E campaign until or even after 4E comes out. Those people deserve a book that’ll be authoritative and help lighten the load at a game session."
That's really classy, regardless of the fact they have to continue to earn revunue from me until 4e comes out. My group will be picking up a happy meal of these. My Amazon order says around the 17th of this month. Looking forward.
