I actually feel the opposite. They're supposed to release locations, venues and coaches this week. As long as they do that they are much farther than the last few efforts. They also have the blessing of USAR, including an announcement on USAR's website.

Their talk of working with existing rugby structures also comes across a lot better that the ways some other groups went about things. Their plan of allowing some overseas players but using a majority of domestic players is a good compromise. There are already plans for Canadian teams to come on board next year.
2016 is soon yes. We will see very quickly if this gets off the ground. But hopefully they did a lot of homework before going public, and have everything in place for this to happen.
