Ace Combat material (betas, prototypes, etc.)

[Bishop]

Hello. I've come to this forum in search of a rare disc put on sale in eBay some time ago by unclejun; more specifically, a "Review Build" of Namco's ACE COMBAT 5: The Unsung War. Having arrived here in search of this gem, I wandered here to ask a question: are there any rare Ace Combat materials, such as betas, prototypes or pre-release discs?

Having brought that up, I'd like to mention a rumor from an AC fansite about Namco having ditched about thousand pre-release copies of AC5 in 2006, which purportedly contain a beta plane called the "ADA-01 ADLER" (read @ http://acecombat.wikia.com/wiki/ADA-01_ADLER), which was revealed in the "ACES AT WAR: A History" artbook released in October last year. May be BS or not, though I'm not sure.

I am a huge fan of Ace Combat, and specifically, consider 5 to be the pinnacle of the series. Probably the best game of that generation, at least from those I played. While unfortunately I have no info on this, I would be very interested in finding more.

The rarest Ace Combat related object I own is a Namco Transmission demo disc which Namco sent me directly to my house back before AC5 was released. It has the trailer to AC5 and a demo of Katamari Damacy, but nothing more. Nothing rare or impressive, unfortunately.
