For the past couple of months there's been WWE TV shows (haven't really paid attention when it's RAW or SD, tbh) that went from 12-14k sellouts to 7-10k sellouts or total attendance, depending on the building the set up they were running. Meaning they cut back on doing shows that barely had a entrance in order to open up more seats. They are still doing it for PLEs as far as I'm aware though, because that demand is still crazy high.
To be fair, there's no world were WWE would've been capable of sustaining the level of tickets sold that they were doing from January to March/April, that shyt was insane. So going "back" to normal setups (80% of an arena + floor seats, and either sell it out or get very close to it) makes sense.
Will be interesting if once January kicks in and The Rock and Bloodline angle once again take center stage, they go back to opening up arenas the same way the did it this year. Like I said, that shyt was pretty fukking crazy.
