Cue the posters calling Metzler a stupidhead.
From the perspective of profit/loss for its owners, the smart move would have been to sell in 2013, when Spike had been expressing an ownership interest and their brand only appeared temporarily weak instead of damaged. Since then, well, the past two years don't need to be rehashed, but the strength of TNA's brand, and hence its value, has shrunk significantly.
At this point, I don't see a way forward for TNA under the ownership of Dixie Carter. She doesn't have the personal resources to fund TNA; the Magic Panda Money fallacy has been debunked about a thousand times now; and no one in their right fucking mind is giving Dixie Carter money today without maintaining control of it. While PopTV appears to have much more reasonable expectations than DA did concerning viewer numbers, they don't appear interested in getting involved in the production end of television.
So disregarding scenarios that involve baby angels flying to Nashville with sacks of money, the best possible scenario now is one where TNA is sold while its TV deal isn't in question, to a group interested in playing the professional wrestling game (see Crockett, J., and Turner, T., with the obvious exception of the TV deal analogy.) The worst case is that Dixie Carter overestimates what TNA is currently worth in a sale, rejects the offers she receives, and one day it's announced that the next set of TV tapings has been cancelled. The WWE swoops in and buys their tape library at an appallingly low sum, being literally the only interested buyer and with TNA needing to liquidate their assets to resolve debts.
Tl;dr- If you enjoy watching a company which calls itself TNA or Impact Wrestling, root very, very hard for either a sale or an investor who is just now coming out of a five year coma.
