ZeniMax Trademarks 'Brink'

And, well, that's about all we know. According to the results of GameSpot's quick investigation, the name "Brink" refers to a new "computer game software" project.
Now, with the 2009 Electronic Entertainment Expo just two weeks away, the name of that project may have surfaced, courtesy of the United States Patent and Trademark Office. On Friday, Bethesda Softworks parent company ZeniMax Media filed an application to trademark "Brink" with the USPTO.

When it is approved, the filing will secure a claim for the name on "computer game software for use with personal computers and home video game consoles; downloadable computer game software offered via the internet and wireless devices." The application also lays claim to "entertainment services, namely, providing on-line interactive computer games and providing information relating to electronic computer games via the internet."
Is it the MMORPG they've been working on for the past couple of years? Or maybe the title they're collaborating with Splash Damage on? Or perhaps something else altogether? Tough to say at this point.
