Someone at marketing company Intellisponse apparently left the latch off the backdoor: A number of sensitive (well, "sensitive" to the videogame world, anyway, it's not like we're talking about national security) documents were not behind enough security, and have since leaked onto the internet. It's good stuff, too... we're talking full Guitar Hero IV details, some potential Call of Duty 5 covers and much, much more.
Although none of this information is confirmed, and marketing companies often will do surveys and other research on projects that never show up anywhere, it may be M'Soft's E3 announcements out more than a month early! So much for surprises. Throughout the morning we'll be rolling out info on everything that dropped, so keep checking back!
