Call of Duty 4: Modern Warfare is up there as one of the best first person shooters of all time in my honest opinion. I think you would be hard pressed to find many people who would argue with that statement. The realism is unparalleled whether it be the gun detail or the uncanny resemblance to a real modern day conflict. You don't feel like your playing a war game, you feel like you're in a war.
Infinity War is looking to up the ante and surpass their near flawless first entry. I'm really not sure what to expect out of this second game but I'm sure us fans will be perfectly content with whatever additions they give us. I have seen plenty of cool new features and I'm sure their keeping the best aspects under wraps for now.
It looks as though they dumped the Call of Duty title in favor of just calling it Modern Warfare 2. I'm not sure if this is because of a licensing conflict or maybe perhaps they just wanted to branch off into their own franchise. But do not be fooled folks, this will be an Infinity Ward Call of Duty Game. Maybe not in name, but the legecy will live on through the amazing action packed, war torn gameplay.

I'm really looking forward to reading your in-depth review of this game. Everything I've read so far sounds amazing.
I found this headline at the Washington Post impressive:

Apparently, Activision Blizzard has donated $1,000,000 to a fund to help unemployed veterans find jobs.
