Marios one of the few things formally announced. Studios opened in 1990, IOA in 1999, and before 9/11 hit (and subsequent bad leadership until Comcast bought it), they were already planning the next gate. Universal's probably targeting a similar timeframe... 2022 gate 3, 2030 gate 4. I think 2030 is too long to hold onto Pokemon (or Mario) if the rights are already negotiated though.
