Since we don't know anything, let's speculate. How would a Top Gear video game work? Naturally, there'd be a driving component where you take various cars around Top Gear's famed test track. Even better than that, you could take various cars around the track as different Top Gear presenters, including the Stig. Perhaps you could recreate some of the classic battles, like when Jeremy Clarkson and the Audi R8 took on Richard Hammond in the Porsche 911 (available after the jump).
Obviously, we could go on for some time here. So we'll just say that we hope there's a Mortal Kombat style level where the boys get to rip each others' spines out, and leave the rest of the speculating to you, our dear readers.
