It actually is going down. Sort of. The budget that was just agreed upon on friday, and that the Govenor has agreed to sign, contains $200 million revenue generated from table games. Of course the problem is that currently table games are illegal in Pa. The fact that they have already included this in the budget that is about to be signed, indicates their intent to change this law. However, I believe doing so requires public hearings and probably lawsuit challenges, which would no doubt be dismissed. However all this still takes time. So, I wouldn't count on seeing table games anytime in the immediate future. Most likely at least a year or so away.
If Philadelphia ever gets it's two casinos built and running, they will become the closest (in proximity) casinos to atlantic city. First, it will be interesting to see what rules Pa adopts for these games, and second to see how AC responds to this threat. They can basically go two ways. Either they can tighten their rules and increase the house advantage to increase revenue from fewer players or can loosen rules (possibly adding surrender and returing to S17 games, and fewer decks) and better penetration hoping to draw more players. I have little confidence they will take the correct route. At least initially.
