I think they hint about it constantly but at the last few festivals they've played, they've been making it pretty obvious. At a festival in LA last month, Kevin announced that this would be their last LA show for quite a while.
I don't think it's quite that concrete. In the Pitchfork interview, Kevin basically makes it seem like BSS is going to take a nap. Talks about how they are a family and families stay together.
I'm pumped for solo Kevin Drew material anyway. His solo record was almost aa good as FRR.
