ZeniMax Media, parent company of Bethesda Softworks (Fallout 3, Oblivion), has applied to trademark "Brink" for computer game software, reports Gamespot.
Beyond that, we're in total speculation territory. Brink could be the secret Wii game, the E3 reveal from Splash Damage or that MMO the company is working on. Bethesda's got a buffet full of projects right now. We've contacted the company for comment.
