I think a company that has a very cheaply produced, weekly televised product that doesn't insult the fans' intelligence will succeed in bringing back another "peak" in pro wrestling interest.
And I don't mean ROH. ROH is fan service; they have some great ideas that can be stolen, but they suffer from (1) too little mainstream exposure (and don't bullshit yourself into thinking being in "The Wrestler" means a goddamned thing), (2) too much talent rotation in the overall roster, and (3) too much top-card concentration.
In terms of a product, there's not much of a card hierarchy. Folks can work the first match one night, and wrestle in the main event the next. That's good because it avoids the whole "Triple H and these guys hog the spotlight" stuff, but it's bad because it makes everyone seem equal. There's little anticipation to say "oh, I can't wait to see so-and-so come out and wrestle!" Guys like Claudio Castignoli and Nigel McGuinness are perfect examples of that.
Second, the ROH product has no flow to it. I sat in attendance at the 1-hour CM Punk/Samoa Joe "World Title Classic" match, and was bored out of my

in' gourd, man. Why? The match was amazing. Looking back on DVD, I was angry that I sat on my hands during the match. But you know what? I was exhausted. There was no "build" on the show. It was 3.5-4 hours of strong-style wrestling: hard hits, near falls out the ass, and a focus on wrestling. No comedy matches, no tits-n-ass. Not that I *want* those things, but a wrestling show needs those things to keep the crowd into the product. ROH wore me out before the main event. I'd seen enough grappling by that point.
It's the opposite of the WWE/TNA product, where we're starved for wrestling matches that are fun to watch, mean something, and have consequences.
Anyone who develops a fine medium, IMO, will be the next company to lead the resurgence of professional wrestling. Something like the NWA of the 1990's.
And, of course, any company that does away with "general managers" and 20-minute in-ring segments. So much storyline can be summed up in a "news" segment, and so much time is wasted with 7 entrances and 10 minutes saying what can be done in 60-90 seconds, with the same reaction.
