Brothers In Arms Furious 4 A "Test Bed"

According to this article on Giant Bomb, Gearbox are saying that the original, serious story for Brothers In Arms might not be over, and that the wacky craziness evident in the Furious 4 trailer is simply a "test bed" for a new direction. The tale of staff sergeant Matthew Baker, on which the earlier parts of the franchise were based, is apparently set to continue. Perhaps when we've finished our long facepalm regarding Furious 4? Something like that.

Phew, maybe.
