Deep Silver announces plans to publish to publish X³: Gold Edition by the middle of this year, offering a collection of both X3 games (X3: Reunion 2.5 and X3: Terran Conflict 2.0) as well as some all-new content called The Aldrin Missions, as well as a soundtrack CD. The announcement covers all territories except North America and the Caribbean, so presumably an announcement for those territories will follow. Here's word on the new content:

The new add-on, "The Aldrin Missions", features the colony of Aldrin, which was lost centuries ago, and is now once again joining the Terran system. The Terrans are quite eager to reestablish the connections between Aldrin, separated from the rest of the universe for so long, and Earth. The Terrans are putting a huge effort into recolonizing the system that had been presumed lost for so long. The player takes on a crucial role in shaping this new Terran frontier, while exploring new Terran stations and facilities, and making use of a new ship and numerous additional features.
