Video game franchises--especially ones as successful as Dead Space--tend to become trilogies, at the very least. Although Electronic Arts has yet to announce Dead Space 3, the game has surfaced yet again--this time as a pre-order on a South African games website.
BT Games is currently taking pre-orders. While there's every reason to believe this is simply a mistake, IGN notes that BT Games has previously outed Mass Effect 3's multiplayer mode and the Jak & Daxter HD Collection. It is reliably leaky, it seems.
Siliconera first wrote about Dead Space 3 back in September. The site claimed the franchise's main protagonist, Isaac Clarke, would return--this time to an icy planet.
