Would be great but yeah I would be extremely surprised if ROH had that sort of money just lying around. Seriously Jeff would be great but can't see him wanting it back and the WWE would be the worst possible choice for everyone. I mean what would WWE get out of owning TNA other than a couple of stars they could easily afford anyway? but having WWE basically controlling the whole mainstream north american wrestling scene would be tragic.
ROH is owned by Sinclair Broadcasting now, and I don't know how that'd work. It would REALLY give them some exposure, but as much as I love ROH, TNA is the more well-known brand, and How would a broadcasting company feel about having it's TOP wrestling show on a network it doesn't own? It wouldn't make financial sense to move TNA to their network of stations, as they're not in a large portion of the US.
But yeah, Sinclair PROBABLY has or could get the money to do it, it's more whether or not that'd make sense.
How about NJPW? They just started broadcasting in english ( or are about to). It'd start to give them NA exposure lol.
