Nope this has nothing to do with the rumor he had been arrested. It was a decision made by his software supplier.
I dont believe the land based casinos will be online in 18 months either.
1. They want players at their casinos where they can maximize profits.
2. While online gaming may be permitted in some states its not permitted in most. Do you really think people in Nevada are going to prefer gambling online over going to one of the mega resorts? If a few do it certainly wont be profitable enough to warrant developing for that limited market.
3. Online gaming would create significantly less tax revenue for states then does land based casinos. You have to consider all the support jobs that go along with land based casinos IE hotel staff, taxis, limos, restaurants, bars, entertainers, dealers, airport staff, airlines etc… Land based casinos create an army of jobs and add billions of dollars to local and state coffers where its permitted. That will be protected vehemently by the Senators and Representatives whose constituents live in those districts. Remember guys this all about money and land based casinos produce far more revenue and taxes then online casinos ever could.
