Looks like Game Update 51 — Elements of Corruption — including the Lavastorm revamp, new x2, x4 raid zones, T3 armor, and fighter revamp have been further delayed.
From a March 9, 2009 post on EQ2Players:
As many of you know, we’ve been working on Elements of Corruption (Game Update 51) for some time…there really is a lot of good stuff coming, including new zones, new raids, new quests, a revamp of Lavastorm, the list seems endless. However, we’re not quite ready to release it. I know many of you were expecting us to do so this week or next, but at this point, we just need some more time to spend working on it so that it’s just right for all of you. Please be patient with us while we finish polishing the update, and as soon as we have a good date that we can ship out all of this exciting goodness, we’ll let you know.
Sad, that its been almost 4 months since a GU and now this was is delay by at least 2 official sony weeks, which in reality is actually 4 weeks.
Again, we here the term Soon!™
