Halo fan site Bungie.org writes:
"Okay, just to clear up a small misunderstanding that might come back to bite Bungie (unfairly) in the future... yesterday, we mentioned that halo3.com had been updated with new content about the game, its characters, weapons, story, and so on. One thing that was immediately noticed by many was the description of the pistol (screenshotted, because it will likely change soon) - it was labeled as the M6D (the designation of the Halo 1 pistol) and described as having a 2x scope. Halo3.com is run by Microsoft, not Bungie - and while most of the content is accurate, some is... not so much. Frankie visited online forums yesterday to clarify some of this stuff, but I figure a front-page post might reach a few more people, and maybe keep down expectations and false hopes. The pistol is actually the M6G, not the original M6D, and it has no scope."
