I am assembling my stuff to sell at Gen Con. I will most likely buy the new books. Do you thing they will be flooded by 3.5 stuff and I shouldn't try to sell my 3.0 books there or will I get a good price for the old stuff?
Personally, I'm hanging onto mine. Even though 3.5 is coming out, remember that not *everyone* is changing to it. What happens if say a year down the road you join a group using 3.0, but you've only got the 3.5 PHB? Quite a sticky situation...
I'm giving mine away, but then again I pretty much do that with all of my books, even the RPGs. I read 'em after I buy them, but if they sit on my shelf for a year without being used, I get rid of them.
