i wonder if some of the industry giants are going to fight the Unity thing at all. not many of them use Unity in their in-house dev studios but many have mobile games and spinoffs they've published and a lot of those use Unity. also even it they don't use Unity, it's one hell of a dangerous precedent to be set for game engines to demand money for anything you've previously released. so MAYBE they'll try to fight it?? but also a lot of them have their own proprietary game engines so they might see what Unity are doing and just copy them :/
