I know that the .45s are coming into the game also the compliance regular, fire bombs, war clubs, and yao guai gauntlets, but is there going to be more? I heard that there was suppose to be tommy guns (Not the laser rcw) but real tommy guns that shoot real bullets. What are you hoping to see in the coming dlc?

well, we just got the holo, so now we need a new "guns" sniper, preferably bolt-action and with a silencer mod.

Yup yup, tommy guns are in If you look closely in the trailer you can see it. A tribal is carrying one (can't recall the time, I'll edit it when I check)
