One of the biggest information leaks I can recall swept through the gaming scene yesterday, as both believable and unbelievable plans for upcoming Microsoft and Activision projects spilled forth.

(Joystiq indexed it all here.)

How did this happen? Is it real? What should gamers make of all of it?

Today, a spokesperson representing the apparent source of all this information tells MTV Multiplayer that there’s nothing to talk about.

“It is our policy that we do not comment on rumor or speculation,” Elizabth McCrocklin of Janine Gordon Associates told me in an e-mail. McCrocklin’s firm represents the Harrison Group, a polling and research group that runs Connecticut-based entity Intellisponse. The information that leaked was all sourced back to Intellisponse.

I replied, asking how this information leak, that was sourced back to URLs bearing the Intellisponse domain, could be considered rumor or speculation rather than a real event.

MTV Multiplayer has also contacted representatives for Microsoft, Activision and Silicon Knights (the last of whom may have had their previously unannounced Sega game leaked). We’ll let you know if we hear anything more from them or Intellisponse.
