Main Card
This should be a good time to point out that the location of the event will ideally be some place like Philadelphia or, yet again, Chicago. Some place where the crowd will be filled with hardcore wrestling fans ready to blow the roof off the place. Philadelphia is my primary choice, however. *EC-Dub EC-Dub EC-Dub*
Also, there will be 10 matches on the main card in total. Perfect to fill a 4 hour show.
Match 1: Jay Lethal vs Cody Rhodes - ROH World Champion vs NWA World Champion
Jay Lethal and Cody Rhodes are two of the most popular wrestlers on the planet. Both of them are extremely marketable and are huge stars in the American Independent Circuit. With their star power on display, this will be a perfect opener to rile up any crowd in the States. The match might even end up being a winner takes all match for both titles. The match will have the stakes and the star power to go with it.
Winner - Cody Rhodes via Pinfall
Cody should get the victory. With WWE involved they will probably have a greater pull at the results and they certainly would prefer Cody winning and celebrating with his brother after the match.
