As reported earlier this week, WWE's decision to book Steve Austin for their upcoming Raw and SmackDown tapings in Madison Square Garden on the 9 and 10 September was motivated by poor ticket sales, with PWInsider's Mike Johnson claiming both shows had sold roughly half their alliance.
Dave Meltzer touched on this in the latest episode of Wrestling Observer Newsletter, stating that the company expect Raw to eventually sell out - though there are presumably doubts over SmackDown.
More interesting are his comments on AEW, however, with Meltzer stating that WWE are trying to block their new competitors from every running the building, hence the emphasis on shifting tickets this time around.
A bold but understandable move from Vince McMahon, given the building's importance to his promotion's legacy. His decision is almost certainly motivated by this year's ROH/NJPW G1 Supercard, which sold the legendary building out in less than an hour over WrestleMania weekend.
MSG seems like a natural place for AEW to host a major pay-per-view, though it looks like they'll need to leap over a Stamford-sized hurdle first. It'll be interesting to see how the dust settles from this.
