I have read where at least two different books have let on that is exactly the case, I suspect it is many more. If they present the next alternatives it only prepares possible enemies in advance for the next round. There are things being worked on right now, you can bet your bottom dollar on that. To much money blowing in the wind for people to say, "you know what you got us. We'll shut down right after this Dallas game". Any industry like this will go down kicking and screaming, not just throw in the towel at the first sign of trouble. Bookies by necessity are people who learn to make adjustments, roll with the punches and move on to the next day. You won't see anyone concede here, if they do it won't be the books. I think you are underestimating these guys.
As far as US money I would suspect it's as high as 3/4's of the money in the CR books and some other places.
