Halo Anniversary playable demo?

Will it happen?

I hope so!

Maybe (probably not though)

Like the halo CE demo for the old xbox?

I doubt it. Players will be able to play it during HaloFest though and Im sure were going to see plenty of video from it as well. Title Update gameplay will also be shown during HaloFest and I am more excited about that one!

Surely there will be a demo on the Campaign level The Silent Cartographer.

Most likely it will be a few months after its released, similar to Halo 3 and Halo Reach.
