Arena Mexico building anniversary video ends with the message that as long as Arena Mexico exists, lucha libre will never die.

It's almost like there's some concern that a certain company is a threat

If I recall Lucha blog reported several years ago that CMLL was trying to sell itself to WWE and the reason it fell through was that CMLL insisted that such a sale include the purchase of their buildings, Arena Mexico being the biggest, and WWE had no interest in becoming a land lord of aging arenas.
