Supreme Commander studio Gas Powered Games is set to make an announcement early next month.
That's according to a countdown teaser site which appeared online this week, ticking down to January 14.
The site reads: "Ready for Something Wild? Be the first to see the next big thing from the designer of Total Annihilation, Dungeon Siege, Supreme Commander, and the team at Gas Powered Games."
The Chris Taylor-helmed developer most recently finished construction duties on Microsoft's Age of Empires Online.
In the same year work on Taylor's fantasy RTS Kings and Castles was put "on hold".
