Geoff Keighly wanted to smash any rumors going around that the Halo: Reach piece shown at the VGA’s this year will not be Computer Generated. He did so by tweeting to his many followers. The tweet read,
Let me put the rumors to rest: The HALO: REACH piece at the VGAs will not be CG.
Whether or not it will be live action or in game footage is still unknown. The one thing we can all count on is it NOT being computer generated. It looks like we have to wait until December 12th to find out exactly what it is.

hmmm well…never was intrested in the halo stuff…thingy, things…anywho maybe this one would be better ….you never know >_> O_o
It will probably be very early in game stuff. In my experience the live action stuff appears closer to release, when they want people to just be thinking “d00d dat looked epic” despite it’s irrelevance in relation to the game.
I’d guess they would shoot for in game footage to get the average joe interested. If they show live action the “uninformed” may take it for a film adaptation.
Well there not Sony bungie is legit. This game will be awesome like every halo game
meh… still not getting that game, halo 3 was the last halo related thing i can take :/
agreed, but if it isn’t such a huge let down like halo 3 and ODST were, I’ll more than likely pick it up. I keep hoping and praying for a good halo game. One that tops Halo: CE
Hmm lets wait and see what happens.
