I think you're forgetting about the biggest con here; Gabe Sapolsky conning Cary Silken into losing tons of money so he could fulfill his dream of promoting a show in Japan. The amazing thing is, he probably originally sold Cary on the idea that it wouldn't lose that much money, because they could sell DVD's based on Samoa Joe wrestling Tenryu, Sasaki, or whatever other big names they could book for this. Yet even after Joe pulled out and the best main event they could muster was Morishima/Nigel (which he ran in Edison, NJ already) and the KENTA/CIMA dream team (which ended up not happening when KENTA hurt his knee), Cary didn't immediately pull the plug. There is almost nothing special about these shows that anybody outside of the ROH base would want to see, and Cary still went ahead and ran the shows at a major loss anyway, just so Gabe could claim he promoted a show in Japan. You have to give Gabe credit for that con, especially since I doubt he lost a dime on this.
Of course, you would think somebody like Gabe, who worked for Paul Heyman for all of those years, would realize that the ultimate goal of a con is to make money, not live out some mark fantasy. Then again, I'm not sure Gabe realizes how badly he was conned by Heyman yet.
