This little piece actually sums up my feelings really regarding the next MW3 and what needs changing and what should be left as it is.
Read the last paragraph about MW3 and thats it in a nutshell for me.

Probably best describes my thoughts as to why i love MW so much.

The shooting components are some of the most refined in the industry. The combat is smooth, fun and frantic without too much of an arcade feel to it and that's more than likely why everyone loves it. Call of Duty has done a lot of great things for gaming in general, but the initial impact of that greatness has worn off and the developers and Activision need to take some of that money they've been stockpiling for years and upgrade the engines. I want to be impressed by the next Call of Duty the way I was with RAGE or the series just doesn't deserve the attention it's getting.
