I wouldn't call something a threat if this thing is an evolution of its precedent. Virtual Reality casinos are not a threat to online casinos because think about this, you'll need internet to access VR casinos. Since you need internet to access them, they'll be a part of online casinos. Some casinos might try to create a dedicated VR casino but I think that long-term, casino game suppliers will create VR games, including VR slots, VR live blackjack, Roulette and so on, and these providers will offer their games to different casinos, they'll implement them and then offer VR experience to their users.
