Gearbox working on Call of Duty rival?

Trademarks filed for World War II Hero, Modern War Hero and other war games...

Gearbox has filed a series of trademark registrations for a new war game.

The registered trademarks are for the names World War II Hero, War Hero, Brothers In Arms War Hero, and Modern War Hero.

Which suggests Gearbox, developers of Brothers In Arms and Borderlands, is shaping up to develop another war game.

Which also makes their comments that Infinity Ward should try something new more interesting. Do they want the Call of Duty developers out of the way so they have no competition for their new war game?
