Did Pink Floyd just casually announce their new album?

Polly Samson, the wife of Pink Floyd's lead singer-guitarist, David Gilmour, nonchalantly tweeted this over the weekend:

Yep. Twenty years after Pink Floyd's last studio album, The Division Bell, the band is coming out with The Endless River.

UPDATE: Spokesman Doug Wright confirmed to AP Monday that The Endless River will, in fact, be released in October. It will consist of "mainly ambient and instrumental music" based on 1993-94 recording sessions for The Division Bell.

Pink Floyd's longtime back-up singer, Durga McBroom-Hudson, also shared the news in a Facebook post: "YES. THERE IS A NEW PINK FLOYD ALBUM COMING OUT. AND I'M ON IT."
