The NHL is waiting for their final vote about expansion from the Board of Governors, on June 22 in Las Vegas. But most believe that the Board will rely heavily on the recommendation of the executive committee - an exclusive group of owners and NHL execs - for guidance in their decision.
The NHL has already said that the earliest they would be expanding is the 2017-18 season.
According To The AP:
A person with direct knowledge of the NHL's decision says the league has settled on Las Vegas as its choice for expansion, provided organizers can come up with a $500 million fee.
The person spoke Tuesday on condition of anonymity because details have not been released by the league ahead of its Board of Governors meeting on June 22. Quebec City was also considered for expansion.
