To Halo Fans:

Could this be?

At the recent G4 Video Game Awards, Halo 3 won Game of the Year chosen by the fans and this was their acceptance speech/video.

In the video there are different characters in multiplayer (possibly bots) and in the last seen, what looks like, a custom map maker. There is tons of internet chatter about these being the new "big changes" that Bungie said were coming in September.

Stay tuned kids!
