With us having 1 new sub and 2 new specials. I'd be shocked if we only got two collections. Unless that second collection gave us like 12-20 weapons at once.
Not counting each individual bomb launcher, all the original specials we have, have at least 9 weapons that use them (8 if you don't count scope chargers). While I'm not entirely expecting these new specials to have that many weapons with them, I do expect more than just like 2 or each, at least 5 weapons with each special. Unless that second collection gives use like 12-20 weapon all with new the new specials, I just can't see it being the end.
I'm honestly hoping that we do just straight up get a 3rd alt for every weapon. Gives them ample room to sprinkle the new subs and specials as well as just make more alt kits with our current existing subs and specials.
Not sure if it is entirely likely, but I can dream. But do note that these new Kensa weapons AREN'T themed as something like Sheldon's Picks, they're treated exactly like any alt kit would, like the Tentatek Splattershot or any other alt.
