*Thinking* Should I buy a product that showcases material that will be in the PHB? Should I buy a product that will probably contain several pregenerated characters and an adventure that is designed to work with only those characters at that level? Should I buy a book to play a single game once or twice when all the information to play the same game an unlimited number of times is being sold in a book only a few months later?
Now as then, NO. I feel no need to buy something about rules that might be changed in the next 6-8 months and designer commentary has always bored me. Once it gets into my hand, it is MY game, not theirs.
Unless they are extraordinaly well reviewed, I'm going to pass. My gaming dollars are limited enough that I can't afford to waste them on books that don't contain the game I desperately want to play (not playing right now unfortunately)
Edit: I'm totally stoked for 4e though. It sounds like WotC has addressed all of the things about 3.5 I have tried to fix on my own, only in better ways
