11 August 2009 — End of the LP
Sasha Frere-Jones says it well. For a better article about Radiohead's opinion than the one he links to, see here and, as it's Stereogum, you have to read the comments for the full hilarity.
Plastic Palace Alice has thought about the possibility of releasing singles or EPs instead of another full-length album, but it's a difficult choice to make at the moment. For now, it looks like an LP is in the works instead, and not for any immediately obvious reasons (and I'm not sure that many bands really think in terms of "single" versus "filler", so much as "possible single" versus "songs we actually like").
