4) Leverage that IP! Not only does WotC have the sole rights to slap "Dungeons & Dragons" on their cover, they have the sole rights to the Forgotten Realms, the World of Greyhawk, Dark Sun and Gamma World. I think Friday's decision means they will be more likely to release these as products in the coming years, as player-facing splatbooks and bestiaries put them on the same playing fields with Kobold Press and the like, and they're not a playing field where they always win, to put it mildly. (And yeah, Gamma World can and should be a D&D setting. Most versions of the game, going back to the very beginning, have been fairly easy to combine with D&D, and creating a post-apocalyptic setting, possibly with more fantasy elements than previously, seems like a no-brainer product, either as a single book or as a slipcase set.)
