Square Enix have revealed that a demo for their forthcoming dungeon-crawler, Dungeon Siege III, is on its way to all three platforms.

Xbox 360 will get the game first, from May 31st, while the PC and PlayStation 3 will have to wait a week for a June 7 release. No specific reason was given for the Xbox 360 head-start, but this is hardly new to the industry these days.

Developed by Obsidian Entertainment (Fallout: New Vegas), Dungeon Siege III is the first time the series has landed on home-consoles proper, and is running off their proprietary engine, but for more, be sure to check out our early hands-on with the game here.

Dungeon Siege III is due to hit all three platforms for release on June 17.
