Gambling regulators are nearing a decision on Philadelphia’s second and final casino license, with the Pennsylvania Gaming Control Board scheduling a Nov. 18 vote that will likely come under scrutiny no matter which of the applicants — if any — win a high-stakes competition involving hundreds of millions of dollars in revenue from table games and slot machines.

The board’s announcement Friday came as Philadelphia’s existing casino renewed its effort to scuttle plans for a second casino in the city, arguing that regulators are operating on “stale information” about the strength of the region’s gambling market.

SugarHouse said in a filing late Thursday a decline in slots revenue in Pennsylvania as well as the industry’s “implosion” in nearby Atlantic City, N.J. — where four casinos have closed this year — are clear signs of market saturation.
