This certainly stings me as a PDF-exclusive buyer and user of D&D.

So what could this mean in the long run...? Here are my thoughts from the WotC forums:

Very likely they're planning to start selling the PDFs online themselves so they can keep the money from online sales. So first step is to take away the permission for anybody else to sell PDFs online.

Same thing happened with all the online character generators and online D&D tools about six months before 4e was announced. And Dragon/Dungeon magazines. Remember?
PS: I looked to see if there was already a thread on this and I couldn't find one, if there is, my apologies.
