Over the years, WWE has made a lot of changes to their pay-per-view events.
Before re-introducing the brand split, PPVs would showcase the best feuds from the entire roster on the same night.
More recently, since Vince McMahon split the company into RAW vs SmackDown again, each brand had their separate Sunday night shows each month.
CHANGING AGAIN
But, once again, McMahon has recently shaken things up. Even though the brand split is still in place, WWE have gone back to co-branded PPVs.
This means that they've reduced the number of prominent events that take place throughout the year - and some shows will disappear.
According to Ringside News, things could get even more interesting as 2018 goes on - with WWE thinking about renaming some of their PPVs.
RETURN OF WCW
The website reports, per Barn Burner, that WWE are going to replace a number of their current PPVs with WCW versions.
Apparently, two shows, in particular, have been speculated to make a return - Halloween Havoc and Starrcade.
Interestingly, Starrcade was used as a name for one of WWE's special live events last year, in North Carolina.
That may have been the first hint that McMahon is thinking about bringing back the PPV that last aired in December 2000.
Like Starrcade, the last Halloween Havoc took place in 2000 - that was the 12th, and to this day, final PPV of its name.
EXCITING CHANGES
As well as a return to WCW names being rumoured, it's also believed that a number of PPVs will be airing at different times this year.
WWE TLC was reportedly scheduled to take place in October, but The Super Show-Down in Australia is now the only show expected to air that month.
Ringside News, per Newsweek, are speculating that TLC will now take place in December, with Clash of Champions airing at a different point in the year as well.
Although WWE hasn't officially confirmed any changes to their 2018 line-up, it wouldn't be surprising to see Starrcade and Halloween Havoc return very soon.
