NCsoft has announced its second expansion for City of Heroes, under the title Going Rogue. The expansion involves Praetoria, a parallel world featuring evil clones of some of City of Heroes' signature characters. Going Rogue will feature a new alignment system to signify that there's not just good and evil, but also shades of grey.

A trailer is available on Going Rogue's teaser site, for anyone wanting a sneak peak at the new expansion.

UPDATE: Further details are available on City of Heroes' official website, with the press release announcing the expansion available here, and a set of frequently asked questions here. In addition to the features listed above, Going Rogue's new alignment system will allow heroes and villains to switch sides, allowing villain archetypes into Paragon City and hero archetypes into the Rogue Isles.
