I think it would do well, like 4-5 million in the first 2 years of release, maybe more.

I think it would easily do COD numbers. The thing is Halo 3 is simply the best arcadey fast paced shooter available on consoles. Now the best shooter period is debatable.

Halo 3 would be a little outdated for the PS3 to get it as a port =/

@DaveD

perhaps graphically........surely you don't mean in terms of gameplay? After all Halo 3 still has things that other shooters on the market still haven't done years later.

I didn't mean gameplay, but people recently want the best graphics and realistic style dates too fast

A shitload. It's not a game only xbox fans would want, it's a huge brand that'd sell very well on the PS3.

Gastronomically....or maybe not....

I think that most people who want to play halo 3 would just pick up a 360.
You can usually pick them up second hand for $100.

Most gamers have multiple consoles to begin with.

Halo 4 multiplat would probably sell 3:1 in favor of the 360 IMO

@ DaveD

very true I wan't trying to jump all over ya, just wasn't sure what you are saying.

That's incorrect.
