I believe they are preparing to do a full-length actually. Have no idea when they'll be able to record it, considering all the guys involved are so busy.
According to the interview on ultimatemetal.com, Mikael says that Anders was mostly responsible for Bloodbath's material. I know that century media is wanting a full length, and I sure hope they release one. I was very impressed with the just the three songs on the EP.
Apparently he's just not interested. He's working on his upcoming Unicorn-esque symph/prog record and has little interest in continuing to do projects... and claims to be more or less done with producing metal altogether.
I can understand where Swano is coming from though. His roots are in prog (go to www.come.to/swano for his reasons) and metal just sort of "happened" to him. He syas he's glad he did well with it, but feels like the part of his life that prog music plays is still feeling incomplete. We'll always have Moontower, Purgatory Afterglow, Panthymonium, Crimson, and the Spectral Sorrows though. And I love Nightingale as well. So shoot me!
