Looks like they are releasing a new album in April. At least in Europe. They also posted on their facebook "The Unseen Empire....beware!" Hopefully it's more along the lines of Holographic Universe and Pitch Black Progress. While I liked Dark Matter Dimensions, it still fell a little flat compared to their previous work.
