As one assumes, there are two Saudi Arabia shows, per the ten-year contract that WWE is currently signed into.
There is no current listing for a women's pay-per-view, but a space of time toward the end of October seems to be open (as was the case with 2018) for one to take place.
In an interesting deviation from the norm, Money in the Bank has moved to May, while Backlash now takes place in June. Clash of Champions also returns to the calendar, taking place in October.
