Original developer Infinite Interactive will be handling the PC version and co-developing the mobile with THQ's Universomo studio; the mobile version will be published and distribute by THQ via its ValuSoft and Wireless divisions. Vicious Cycle, recently acquired by D3 and who previously worked on the PSP version, will be co-developing Puzzle Quest for Wii and PS2.
Conspicuously absent from the announcement is mention of a PlayStation 3 version, either as a retail product or the more likely PlayStation Network download. We've contacted D3 for information. In the meantime, check out the highly addictive PC demo of the game.
