Hell might freeze over if that ever happened. TNA has got better, but they still fall short of being taken seriously. But, if we are speaking in hypotheticals, TNA will aquire the talent of WWE. But, will still be unable to grow in popularity, these WWE guys will not make a pay cut for TNA and they themselves would go out of business. Wrestling is dead forever. Although, I imagine some of the bigger stars that are more business savvy would break off and form their own promotion, with TNA still being reduced to number 1. In short, even if WWE goes out of business, I cannot see them ever being number 1.
