Update: The Oct. 27 date applies to pre-orderers only (both 360 and PC), Shack reports. Some retailers are reporting that a public demo will follow on Nov. 3rd, though EA isn’t clarifying on that for the time being.

Original story: Mentioned during EA’s Tokyo Game Show press event Japan was the release date for a Left 4 Dead 2 demo. Valve’s Kim Swift announced that they are intending to release a demo for both PC and Xbox 360 next month, on October 27. The exact contents of the demo are unclear though we’re sure they’ll be clarified upon as TGS ramps up this week.
