That job listing was correct. City of Heroes developer Cryptic Studios is working on a Star Trek MMO, and its got the screenshots to prove it. Dubbed Star Trek Online, the game will be based on the Star Trek franchise. Says Cryptic chief creative officer Jack Emmert:

Star Trek was never about a single character, ship or even planet; Star Trek was always about an entire universe. And MMORPGs are uniquely suited to create such a thing and allow players to explore every inch.

First gameplay footage as well as more details about the game will be unveiled at the annual Star Trek convention in Las Vegas on Sunday, August 10th. Those unable to attend can check out the live webcast at the game's homepage.
