Yeah, I just saw that thread. I honestly don't think there's going to be THAT big of a change. Just some clarifications on some rules and spells (shield, harm, polymorph, haste, etc), but nothing that none of us probably haven't been made aware of in the past.
As I have the 1st printing of all the books, I wouldn't mind having a revised set of books if it helps clear up some of the more confusing areas (magic item creation seems to generate a lot of questions, grappling, etc).
I know me, and I know I'll be buying them on the day they are released (I'm so easily parted from my money)
