Aliens: Colonial Marines, Samba de Amigo, Brothers in Arms, Borderlands - Gearbox Software certainly has a busy line up of titles over the next twelve months, but that hasn't stopped Gearbox Software from planning ahead for the future.

Studio head, Randy Pitchford first revealed that one upcoming and unannounced project as something 'big' earlier in the year, and now it seems that the rumour mill has stopped at one possible brand: Halo 4.

The latest suggestion comes from the North American edition of Official Xbox Magazine, which includes the rumour that the fourth outing will be a launch title for Microsoft's third console.

Naturally, this one will remain in the rumour domain for quite some time, though the suggestion that Gearbox is working on Halo 4 is far from ridiculous...
