There hasn't been any official reports. but some interesting information has come to light, and that information may reveal the name of the new Las Vegas franchise that was granted an NHL expansion team this summer.
According to a report from Justin Emerson of the Las Vegas Review Journal a number of internet domain names have been registered, and they clearly point towards the names belonging to a hockey team, furthermore the names have been purchbased by a company known to have ties to the National Hockey League.
Last week the domains lasvegasdesertknights.com, vegasdesertknights.com and desertknightshockey.com were privately registered to Moniker Privacy Services, which is the same company that procured the domain name to NHL.com.
This is of course is not official confirmation of anything, but the information certainly leads us to believe this could be the name of the newest NHL franchise.
