THQ boss Brian Farrell has said there will be more Darksiders, Saints Row and de Blob next year.
He told investors during a conference call (reported by Kotaku) that new instalments in each series will appear after April 2011 - the start of THQ's financial year 2012.
That's a quick turnaround for developer Vigil, which only released Darksiders last month. Nevertheless, the game sold well and impressed critics.
Saints Row 2 appeared in October 2008 and faired similarly well. Eurogamer scored the game 9/10 for its deliciously over-the-top openworld antics.
Wii exclusive de Blob was released in September 2008 and, although not typical series fodder, was a strong and welcome addition to the console's third-party line-up.
