I have read that the OGL for the d20 system runs out soon, and that the new license will only be for 4.0 fantasy or non-fantasy 3.5. Does this mean that wotc would possibly sue Paizo for Pathfinder? I have read some of the wording in the newly proposed license and though I have not fine-tooth-combed it, that is how it seems to me.
I am, of course, referring to this: http://www.wizards.com/default.asp?x=dnd/4news/20080417a
Though you can dig through the forums on Gleemax and find other indications.
I am not trying to start an argument, btw, just voicing my concern.
