I think the UFL is going to survive... I have heard hopes that the league's higher-ups are trying to shape the UFL into an NFL development league...
I'd say if they solidify a relationship - no matter how in depth or whatnot - with the NFL, it should fare pretty well.
I think Omaha was also a great choice for their newest franchise. People here have really embraced the Nighthawks this season, let's hope that carries over into next year and this wasn't just the new novelty in town
