If you've already played your way through Dragon's Dogma, Capcom wants you to do it again. They've confirmed that they will be making new modes and content available in the coming months, including new Speedrun and Hard modes. Both will be available free of charge, and before the end of the year. Speedrun will challenge you to play through the game as fast as you can, with in-game equipment awarded for clearing specific times. Hard Mode basically just turnes the difficulty up to 11, but rewards you with extra bonus equipment.
And in 2013, Capcom is preparing Dragon's Dogma Dark Arisen, a major expansion to the game, but there are no real details about it at this point. Heck, the title of it hasn't even been approved by Microsoft!
