Epic's Cliffy B (Cliff Bleszinski) will unveil the studio's new game on the Jimmy Fallon TV show in the US on Thursday next week.
Fallon - whose Late night show airs on NBC - revealed the news in a Tweet last night, which read:
'Game designer Cliff Bleszinski (@therealcliffyb) debuts his new game on Late Night next Thur. Set your TiVos! And your Xboxes.'
No surprise, but at least now we know it's coming to 360...
Bleszinski promised some 'Megaton, face-melting news' in January which, erm, never really arrived.
We're hopeful this could be it.
What could it be though? Surely they're saving Gears Of War 3 for E3?
