This press release has word from sunny Iceland that the Trinity expansion for EVE Online will be released for free to subscribers to the outer space MMORPG on December 5, a user-base that CCP announces has crossed the 200,000 player threshold. A complete list of new features can be found here, and a trailer for the expansion is on this page. Here's a bit on Trinity that describes its emphasis on updated graphics:

The release of the Trinity expansion fortifies EVE Online's position at the forefront of three-dimensional game graphics, creating a breath-taking cinematic experience during actual gameplay. In order to achieve its visual goals, CCP developed a new graphics engine, architected for Shader Model 3.0 and above. In this first showcase for the new engine, all ships, stations and stargates have been reconstructed. EVE Online: Trinity employs advanced lighting techniques and complex surface materials to make these highly detailed models even more realistic.
