The M4A1 model is different, as well as the EO Tech sight and Delta Force soldiers. The knifing animation is tweaked from the Modern Warfare 2 version, and the exact knife model is/will be different, as has been the case with pretty much every game in the franchise. Not to mention that a lot of things will change from this state, as they still have a number of months before going gold.
