from what I hear...
Media: The new Langster steel is Specialized's first foray in to the world of Keirin racing. It will be the only mass produced NJS stamped Keirin framest made outside of Japan. Specialized have teamed up with Dokuru and will be providing frames and componentry to a Keirin team in 2010. Langster steel sold as frameset only, expected to arrive in Continental US stores by August 09. MSRP $650
I also read that they're the same as the new khs's and are both produced in one of colnago's factories. (colnago is the only non-japanese njs certified builder.)
