I'll be interested what happens to airfare and hotel prices on game weekends. Ticket prices will be interesting too. Small local base with a fair distance to other major cities. They really will be relying on visiting team in my opinion.
I think you will be surprised how many people Vegas can absorb. They have some very large conventions in Vegas, SHOT Show, SEMA, CES, NAB, etc that routinely carry over 100K attendees. (https://vegasinc.com/business/public-record/2014/dec/28/list-largest-conventions-2014/)
Vegas will be the new San Diego in the Super Bowl rotation. Its a destination that should have decent weather even though it can get cold and windy.
As long as the Super Bowl weekend doesn't fall on the same weekend as one of those big conventions then Vegas will be sitting sweet for games and rooms.
Also one thing about Raider fans, a VERY large contingent flies up from SoCal on game days and flies back right after the game. The Coliseum is maybe 2 exits away from the airport in Oakland. They run special Southwest flights up and down for this group of fans. I believe you will see the exact same setup for them in Vegas, except you'll see people from NorCal and SoCal now flying in for these games. Its only a 3+ hour drive up I-15 to Vegas as well so many will also drive v flying with it closer than being in Oakland.
