GenCon starts tomorrow; the target is almost inevitably the announcement of Dungeons & Dragons 4th Edition.
the_gneech, might as well table your Star Wars Saga Edition Sword & Sorcery conversions; D&D4 is almost certainly going to look very similar to SWS.
The Rumor Mill is pretty certain that 4th Edition will not be OGL; the Noble Experiement of d20 licensing and Open Source Gaming may be dead. Word is that the Hasbro suits have never liked the idea of giving away the milk from the cash cow. Of course, the genie's out of the bottle -- they can't make the last seven years of OGL/d20 product just go away, and I'm sure there are going to be people using the old SRD as the basis for their homebrewed games for years to come.
At least when superhero comics do a massive Retcon Crisis, you don't have to throw out all your old comics...
