Update: Valve sent over word that the PC pre-order demo is now available as well.

Original story: There’s been a bit of a delay with the Left 4 Dead 2 demo that was supposed to be out for both PC and Xbox 360 pre-orderers today. Even though pre-loading started several days ago, the PC demo today remained and is still very much locked. The delay won’t be a long one though as Valve has sent over official word saying that, while the Xbox 360 version is now up on Live and ready to be downloaded, they’re hoping to make the PC demo available tomorrow, Oct 28.

The public demo is expected to launch next month, on November 17.
