To reitterate, taping on the road costs a LOT more money and they arent willing to pay for it. Spike have chipped in for their recent excursions, but are now discouraged since the outside tapings dont make the ratings any higher (which is why they build road tapings up more than PPV as special events, searching for a bump) so they dont see whats in it for them.
On the point of "now they're pushing the young guys", that may be so to some degree (although lets not go crazy..), but however much thats true, at the same time my feeling is that its just too little, too late. I dont care about TNA or whether they're a success anymore. I dont care about almost anyone there or if they finally get to main event in TNA. I cared years ago, I even cared a couple of years ago, but they missed their numerous chances and burned me too much, and now I dont care. And it seems like a lot of people feel the same way.
Thats not to say I couldnt enjoy the show if I found something I liked, but as far as investing in the bigger picture of TNA and its success, I couldnt possibly care.
