A recent job listing from Microsoft has shown it's working on a "large franchise" for Natal.
The listing for a Senior Level Designer has the keywords "mission/environment design", "combat" and "strategy".
As for what that large franchise is, it's unknown what that could be.
Yesterday, Xbox exec Aaron Greenberg said Natal will oversee a five year lifespan. He also teased the full name for the motion camera could be revealed at E3, although, for now, it's still in codename status.
The full listing is below. Natal was confirmed for a Holiday release at CES.
