Wanted: Pre-release versions of Wipeout HD

[MrOrbital]

Hi.
I'm looking for pre-releases for this title. I'm offering $250 for a pre-production disc that is dated between march to may 2008. Anyone interested?
I should mention that I already have the press kit. I'm now looking for earlier versions of the game due to that the original zone mode was missing from the press kit and the retail version.
