This was in the new weapon types devlog (emphasis added):Quote from: Styg on February 21, 2017, 06:11:41 pmThe process of adding these new weapons took a long time because we had to change the way we handled animations of all the different human models and it required a lot of manual labor to get things in order. However, now that we have done this, it will allow us to add more new weapons in the future (not in this DLC, though), to which we are rather looking forward to. I'm not gonna lie, we already know what weapons we want to add in the future, so just keep that in mind when you're posting your wishes.Whether that includes [laser rifles and chem rifles], I guess we'll just have to wait (a long long time ) and see.
