A document that appeared on Sega of America’s official press site recounting an August 5 company meeting with Sony representatives covers everything from Aliens and Bayonetta to Sonic and something called Vanquish.

The document had been accessible early Tuesday morning. It appears to contain meeting notes, many of which detail Sega’s games. It seems to have been first spotted on French website, Objectif-Sega but has since been removed.

If real, the document portrays conversations between members of Sega of America and Rob Dyer, the senior vice president of publisher relations at Sony Computer Entertainment of America, in what is indicated as a quarterly update with Sony regarding Sega’s plans.

Every major Sega game is mentioned in the document, often with details that appear to be either upcoming plans or at least ideas about what would the companies might pursue.

The document mentions a Bayonetta collectors edition that would include an action figure. No such edition has been announced. It indicates that a Sega product evaluator deemed the first level of this fall’s role-playing game, Alpha Protocol, as too difficult at the time and described it barely feeling like a role-playing game.

The alleged Sony-Sega meeting notes include multiple mentions of Sega working with Sony-specific initiatives. Sega’s Vancouver 2010 Olympics game, Iron Man 2 and Aliens Vs. Predator are listed as candidates for spaces or avatar item downloads in the PlayStation Home virtual world. The notes mention the possibility of Sony-specific characters appearing in a PlayStation 3 version of 2010’s Sonic & Sega All Stars Racing, though the notes strangely disqualifies a Sony mascot in favour of Microsoft-owned properties: “Open to DLC to differentiate PS3 SKU [version] – not ratchet and clank but other characters maybe characters from Rare or Fable universes.”

The document covers cult favourite series Yakuza, which has had two releases in the U.S. Two other Yakuza games, including the current-gen Yakuza 3, remain Japan-only games. Of the Yakuza games, the notes state: “Could put Japanese games directly on PSN for download in a special Japanese Import section (pricing $US9.99 to $US39.99 for full game). Might need to localize menus at least with subtitles. SCEA interested in helping on MKTG side if they can have period of exclusivity.”

The possibility of interaction between the PlayStation 3 and PlayStation Portable is mentioned for Aliens: Colonial Marines, a game that was not yet announced for any portable system. The same option was also mentioned for something called Vanquish.

The final Sega game property mentioned in the document is Sonic, which is considered in the notes as a candidate for a “Best of Sonic” collection. The notes state that “SCEA would love PSN exclusive power ups/different game modes.”

The document also included notes about Sony’s plans for its motion controller and digital download store.
