Greetings!
Well, yeah, I'll buy the books. Most of my friends will certainly leap into it full-bore, so I will definitely get all the damn books.
I'm not thrilled with the timing though, and the thought of invalidating my entire library of 3.5E books, that I have spent thousands and thousands of dollars on, well, I'm angry for damn sure.
But I'll buy the 4E books.
Semper Fidelis,
SHARK
