THQ is growing and they've already grabbed Itagaki's Valhalla Games Studios and Tim Schafer's Double Fine. Now they claim that they've signed up another big developer, but we'll have to wait until the announcement on October 19 to find out exactly who it is.
Recently Bungie joined forces with Activision and Insomniac Games with EA, so it will be interesting to see who THQ managed to snag and what game is being worked on. We'll find out who next Tuesday, unless the rumor mill manages to unearth it ahead of time.
