Personally, I don't believe there will ever be a North American MMA organization that can ever truly compete with the UFC. The IFL certainly can't, bodog can't, and K1 surly can't. As far as I'm concerned, the UFC is the elite!
Over the next 100 years if our sport is still kicking, other big events will prevail as well.
