The leak torrent from marketing firm Intellisponse regarding upcoming Activision and Microsoft projects, games and peripherals is indeed *mostly* the real deal, said one industry insider with first-hand knowledge of the events.

While not all the information contained in the massive Sunday evening leak can be confirmed as of press time, a source told GamePro Monday that anything with screenshots, box art or guitars in the title was legitimate.

This would seem to indicate that Call of Duty 5 is dropping the "5" for a "World at War" subtitle; that Guitar Hero: World Tour will feature a new touch sensitive guitar, and go for US$180; a game show channel is headed to Xbox Live; and balance board games are coming soon to Microsoft and Sony branded systems.

The news would also mean that Microsoft is ready to attack Sony's SingStar with Lips, which will be a "music and singing game that includes 30 songs, 2 wireless interactive microphones, the ability to use and sing your own music or downloaded songs from an online service," according to posts at NeoGAF.

Intellisponse, for its part, has denied everything. When pressed by Kotaku via email, spokesperson Elizabeth McCrocklin said "it is our policy that we do not comment on rumor or speculation." Kotaku has a round up of the rumors (or are they facts now?), up today.

Still unknown at this time is the fate of Microsoft's updated Mii-like avatar system for Xbox Live. On Sunday, Gamepro reported on a leak that said Microsoft was experimenting with a customizable replacement for GamerTag pictures. Microsoft has not replied to requests from GamePro editors for comment on this information. However, there is an image of the new vatars contained within the leak materials, so you might as well chalk this one up on the fact side of the board as well, right?

More to come as it breaks...
