The rumours are coming in thick and fast as to what we can expect to hear from Microsoft at this evening's E3 keynote speech. Bungie has made no secret of its plans to make a big announcement at the Expo and what better time to do it than during the first of the three major keynotes, when the eyes of gamers all over the world will be watching!

No-one knows for sure what Bungie has up its sleeve, but Joystiq has apparently received a photograph of an image that's been doing the rounds on Wal-Mart's intranet, which shows that a shooter called Halo "Blue" is scheduled with a tentative release date of September 30th.

Gamespot claim to know more information on Halo "Blue" stating that it will be a "darker, grittier" squad shooter in the vein of Ghost Recon or Gears of War.

Is there a brand new Halo game on the way? Or could it be the release of a Halo trilogy pack?

We should know for sure this evening. Microsoft's keynote kicks off at 8pm GMT. Stay tuned.
