Trials HD, the XBLA version of the "don't try this at home" motorcycle stunt series, has surpassed 2 million units sold. Developer RedLynx says the figure covers the "digital numbers" and clarified to Joystiq that it does not include the recently released XBLA disc bundle.

Trials HD launched 18 months ago and had sold a million units by September last year. RedLynx isn't ready to share what its next HD project is -- though we do know that it currently has "six teams working on six games."
