Infinity Ward is not CryTek, they aren't purposely going to make the game demanding. Remember, these guys make a lot of money though games that appeal to people and it spreads by word of mouth a lot! I expect it to be something not overly demanding, and acceptable in terms of requirements for the gaming demographic.
