You are basing your doubts on what exactly? Surely not the superior population-noble heritage nonsense of your earlier post?
Population dispersal - Saskatoon ranked 21st in Canada in population. Regina 24th.
Corporate sponsorship - You know that really famous Saskatchewan company that can get behind the idea of spending a billion dollars on bringing a NHL team to Regina or Saskatoon? Encroaching on any/all of Calgary, Edmonton, Vancouver, Winnipeg territories? Me neither.
Lack of NHL arena(s) or plans to build one in the near future
Lack of support or drive behind the idea (See: Quebec City fans invading arenas in the NHL a year ago)
No history of NHL teams such as in Winnipeg.
