Kalypso Media and First Star Software announce Boulder Dash-XL, a sequel/remake for the classic platformer in development at Catnip Games for release on Windows and Xbox 360. The news is accompanied by this batch of screenshots, and here's a bit from the announcement:

Boulder Dash’s tricky puzzle and dexterity-based gameplay made its debut in the early 80s and continues to entertain its enormous fan base and new players. The game is recognized as one of the best-loved retro games in the history of computer and video gaming. Now Boulder Dash®-XL™ brings this classic back with a hot new look that will take the Xbox LIVE Arcade and Windows PC platforms by storm. The game’s core remains unchanged: in a race against time players must collect sparkling diamonds while besting hordes of enemies, while avoiding numerous traps, and keeping an eye out for falling boulders!
