In the immediate future, players are getting crowd-control balances, two level-80 group dungeons, and a faction progression revamp, all of which are slated for the next update and currently available on the test server. Following that, we can look forward to The Forgotten City and The Breach, two new solo auto-content generation dungeons designed for levels 40 to 80. There are also a handful of technical improvements, optimizations, and general balancing scheduled to accompany the new content, and of course the much-anticipated Blood and Glory PvP server ruleset is coming sometime this summer.
Finally, Morrison teases fans with a blurb about AoC's late-2011 updates, specifically "two new and important elements incoming." He also hints at some sort of tie-in with the upcoming Conan film reboot. Head to the official AoC boards to see for yourself.
