There's one thing that might be hinting the next perks though which are the off perk weapons we have available to us, the Flamethrower and the Katana, the Flamethrower is obviously a Firebug weapon while the Katana is a martial artist weapon.



Since they already have these weapons in the game, it might be an indicator that these perks might be closer to release than other perks since they are already available to us, but this is only speculation on my part.
