Unless they have full control of the websites, no. Why would anybody bother to go to a casino if they can have the same experience sitting at home? I think attendance at the brick and mortar casinos would have to decline.
Frankly, I don't really give a shit. I don't gamble or go to casinos - tried it, got bored, don't do it anymore.
If you GHDC guys want to go that direction, I don't care either. I just don't see how it can help us SFMI guys.
