I wish for no real world weapons - looks like I may have gotten my wish.
Yeah, but many of the weapons appear to be somewhat futuristic adaptations of real world weapons which is a pretty neat idea in my opinion. That said, to those of you who requested the MP7- the "Hockler" machine pistol offered in the Steam Spec Ops DLC appears to be an adaption of the MP7 without the foregrip or stock extended. Also in terms of what I'd like to see...not sure actually. I can't bring to mind the weapon selection screen at the moment so I'm not sure how many are already added but a few more bullpup weapons would be neat.
EDIT: Sorry, did not see that so many people already mentioned the Hockler. My mistake. Also, if balanced/not a major feature (i.e. hard to get like in Enemy Territory: Quake Wars) I could see dual wielding of some pistols/machine pistols working. SMGs, though- contrary to what MW2 suggests- should be out of the question. The amount that this has been featured in promotional videos suggests that we will be getting it but at this point I don't think it's been confirmed or denied.
