G1 Supercard at MSG Wrestlemania weekend sold nearly 6,000 tickets during their presale. Today the general public took less than 20 minutes to sell out the remaining 13,500 seats. This event is already more successful than most imagined it would be. Remember that WWE had tried (and failed) to keep MSG exclusively for themselves, however, WWE dropped the ball and it allowed for this show to take place. It's a promise step for any non-WWE organization to sell out MSG. Some tickets are still available on secondary websites like Ticketmaster but that's because they buy a chunk upfront and sell them out over time.
