As Super Rugby expansion looms, the Pacific Islands appear set to be left out in the cold, yet again.

This year, the three Sanzar nations will debate whether to expand the competition in 2016, as part of a new broadcast deal.

The introduction of the United States and Canada into the Pacific Nations Cup, and comments from Sanzar chief executive Greg Peters this week, confirmed those countries were being viewed as possible destinations.

Asia and Argentina are other contenders, but, until now the Pacific Islands haven't been mentioned.

In 2013, pessimism continues to prevail about inducting an island nation or a combined team into Super Rugby.

Money and resources remain major barriers.

Former Samoan captain Mahonri Schwalger would jump at the chance to lead a breakthrough island venture, one that would create pathways for aspiring players and strengthen Pacific rugby.

The performances of Samoa and Tonga at the World Cup and during last year's European tours have only enhanced the argument to assist their success.

"Samoa has been trying to break into the competition for the last 10 years," Schwalger said. "The thing we released is it's all about money. All the islands struggle financially. It comes down to sponsors and money to get our best players.

"That's the only downfall about the islands; they don't have the resources to compete with the big countries.
