I can't recall a game that has been leaked 4-5 months prior to release and a high profile game like this will definitely be targeted but also well protected by IW I'm sure until it's in less trustworthy hands like retailers which like I said is typically within weeks of release.
It would be nice to see a copy this early though, PC or 360, personally I'd like to see PC leak get a head start on coding a hack for it and pwn noobs on release day.
