So far we know of a few returning weapons, the AK, the 1911, the mp5. I'm sure those won't be the only ones, so it's possible. The MP5 they have in this one is a little different, more like the secret service type variant that has a foregrip & no stock, so if the vector returns, maybe it'll be altered slightly... I'm still crossin' my fingers they add a new SCAR-esque AR...
