This Sunday, in Los Angeles, WWE presents No Mercy, the only pay-per-view of September.
Today we found out that there will only be one pay-per-view in December as well, and it will be a SmackDown event. Clash of Champions, which was a September Raw event in 2016, will be on December 17 in Boston.
There are two pay-per-views in October, SmackDown's Hell In A Cell on the 8th in Minneapolis, and Raw's TLC on the 22nd. Survivor Series is one of the "Big Four" dual-branded events, and is in Houston on November 19.
Both Raw and SmackDown will be at Chicago's AllState Arena on December 25 and 26, respectively. January's Royal Rumble will be held in Philadelphia on January 28. After TLC on October 22, there will not be another Raw-exclusive PPV until at least Feburary.
