7. Olympic Stadium (Montreal, Quebec, Canada)
Why it might: Another stadium fitting the WWE magazine tease, it is after all called the Olympic Stadium. Much of the same reasoning for Toronto will apply here as the dedicated Canadian fans deserve a long overdue Mania. Nicknamed the Big O (not to be confused with Zack Ryder's pal on his youtube show), it is a fantastic stadium aesthetically, that sort of resembles the Starship Enterprise, with the equally fascinating Biodome - a great hotspot for tourism - nearby. Revenue of the event can go a long way for the local taxpayers, who helped build and maintain the costly stadium out of their own pocket.
Why it might not: Every WrestleMania trip to Canada has been to the Rogers Centre and there's no reason to suggest this would change in the foreseeable future. The Olympic Stadium is said to be on its last legs, with no tenants and a history of financial and structural problems. Cracks can be seen and pieces are falling off - meaning heavy maintenance will be needed, perhaps even more than that done for the Citrus Bowl in preparation for XXIV. It's a calculated risk probably not worth taking when you have so many other venues readily available.
