This new Call of Duty looks really different from Infinity Wards take on it. I think that COD5 will have better options that COD4. If you go on the Infinity Ward website and read most of the posts, they are all negative.
Activison seems to be polling the people to see the likes and dislikes of COD4, so I think that may make it better than COD4... but I'm still not sold on it. I'm so used to COD4, that I might wait awhile before getting it. I have never played Gears, so I'm pretty one sided on this issue.
