They will almost certainly have affiliate programs since it will be just as competitive between all of the land-based vegas casinos online as it is on-strip, so any competitive advantage to be gained would seemingly be pursued. The worry I have is how much they will squeeze affiliates. I can envision an Amazon scenario where you get 2% of the winnings for the first month of a player, or worse yet a $20 CPA or something. Not sure exactly why I think that land-based casinos would offer so little to the affiliate community, but it has something to do with the name recognition that MGM, Bellagio, Mandalay Bay, Binions have already established. But then there is the other side of the coin where the smaller casinos can offer more and take more of the online business, putting the pressure on the bigger guys to offer the same.
