Dodger Stadium, Fenway, Wrigley, Anaheim, Rogers Center/Skydome, Kauffman already has a replacement plan.
Interestingly, Toronto recently built a 50,000 seat stadium for concerts ONLY.
"On Thursday (Sept. 26), Live Nation and Northcrest Developments announced Rogers Stadium, the new 50,000 capacity outdoor venue in Toronto opening in June 2025. The venue will instantly become one of the biggest in Canada, with a slightly higher capacity than Toronto's other stadium, Rogers Centre (home of the Toronto Blue Jays baseball team). It's also one of the world's few venues of the size that isn't also home to a sports team."
