WWE currently has two more Saudi Arabia shows booked for 2019. One in May and one in November, according to the Wrestling Observer Newsletter. They haven’t been officially announced yet and WWE will likely hold off on the announcement as long as possible to keep the heat away.
There were two shows in 2018, so it seems like it’s going to be two shows a year for the next 10 years…
The Observer also noted that talent bonuses for the last Saudi show just came in and “some are happy and some are not.”
