Haven't you seen the other threads about the new guns?
They're most likely getting nerfed. But I wish they didn't do anything with them and leave them as they are now, because the M4 was (2010) $4,500.
So I guess it's kind of a 50/50 thing here. But you know, if you know how to use M4's they can be better than any gun. So it's not just about the weapon, it's about the one holding it.
