I think there's already a decent amount, but I do hope that there's going to be a continuous stream of new weapons and clothing. People shit on DayZ, but that game has tons of items that are constantly added.I do hope they add some more weapons going forward. There's a good variety as it is but more couldn't hurt in each class. I've never seen a Tommy gun or SAW yet either
At least it's already better than H1Z1 which somehow managed to add only one extra rifle after two (!) years of development to an already miserable offering of guns.
