The simple thing is that no matter what the Ps3 fanboys says. its just that they can never get Halo 3 in that system that is the main reason of their jealously. Halo 3 is going be a visually and gameplay wise i.e. i really mean in multiplayer LIVE , its gonna rock... and i dont think any other games can compete with the fun that you have on Live while paying halo. All the peple who played Halo2 LIVE know what i'm talking about.

Halo 3 LIVE's replay value will be probably over a 1,000 times.

Halo 3 will recieve 9.5 + from gamespot.

Halo 3 will be the 2007 Game of the Year, even if any AAA games were released (including MGS4).

Halo 3 will sell 5 Millions + copies easily.
