The accoustic one, or the new studio album? The last thing I heard about the studio album is some unspecified time next year. I think very early in the year, they said they planned on working on it in '09, but Sharon getting pregant and giving birth put that off. I haven't heard any more recent news, and there's nothing on their website.
I did notice that they have some tour dates scheduled in Europe in March and April. And according to Wikipedia, "In an interview on the dutch website Nu.nl the band announced that their new album would probably be release in the autumn of 2010, after finishing their second accoustic theatre tour, planned in April 2010." I'm certainly hoping they bring the tour over here to the U.S. Sucks that it looks like a new studio album won't be out for about another year though.
