We've heard nothing yet about Spike renewing TNA's TV deal.
If Spike drops TNA (since really, Cops gets the same or better ratings), is that the end of the promotion right there? They can't survive on just house shows given the low attendance, right?
Yup, TNA exists on the whims of Spike TV and nothing more. Most people think that Spike is just waiting to see how the WWE deal shakes down, and then if they don't get WWE they'll offer TNA whatever they offer and TNA will happily accept and continue surviving. If WWE goes to Spike, TNA is done.
