According to CCP's latest dev blog entry, the EVElopedia wiki on the game's official site will soon be getting a facelift. As you can see in the above image, the team has "fixed ugly into new sexy." They're also removing the moderation queue, fixing their backend, implementing a content portal system, and adding more content from the EVE University and EVE History wikis.

As for as the not so distant future is concerned for EVElopedia, CCP wants to improve the wiki editor to make it easier to use, localize it in more languages and make it so the help button takes you to an appropriate wiki article. They're also working on the first part of the Immersion Project, which is a "central storehouse" of all the game's lore.
