On December 11th, Allakhazam had a developer chat with the EQ2 development team on Dec 11th.

Some relevant quotes:

Anon: Is there any plan to at Raid x 2 content to TSO?

• Ilucide: Yeah, absolutely. Though not necessarily ‘part’ of TSO, we will be adding a pretty nice sized chunk of x2 content in the not-so-distant future. Keep your eyes peeled, it will be part of a larger content release with a new x4 zone, and a whole bunch of new solo content in Lavastorm for level 80ish players.
• Ilucide: Timetravelling and Kander are hard at work on the x2 zone, and it’s shaping up beautifully!
• Ilucide: (Addendum: Domino totally reminds me that she’s got something special for tradeskillers as a part of that content update too.) *ducks*
