In the latest Wrestling Observer newsletter, Dave Meltzer noted that the reason why WWE is swapping days for NXT Takeover and the WWE Hall Of Fame during WrestleMania 33 weekend in Orlando is because they have the luxury of using the same building for everything (except Mania, of course). If the Hall Of Fame were to take place on Saturday then they’d have to set up the arena on Friday for NXT, take down the arena setup and set up the Hall Of Fame seating and stage and then take that back down again so they could set up the arena for Raw.
This year they would set up the Hall Of Fame stage and seating and then they would only need to set up the arena for wrestling. They would only need to switch out the sets after NXT for Raw and Smackdown.
I was told that wrestlers were happy about this because it gives them time to rest up instead of staying up late because of the Hall Of Fame ceremony. In previous years, wrestlers would attend the Hall Of Fame, stay up late and then would need to be at the stadium early to get ready for Mania. Then there’s the Mania after party and then they would need to be up early to get ready for Raw the next day. At least this way they can rest up on Saturday since that is the day for NXT Takeover.
As previously noted, the schedule of WWE events (aside from Axxess, media interviews, etc) are as follows: WWE Hall Of Fame on Friday 3/31, NXT Takeover on 4/1, WrestleMania on 4/2, Raw on 4/3, Smackdown Live on 4/4. All of those shows will take placea t the same arena and Smackdown Live is now considered part of the WrestleMania weekend shows. There has also been talk of taping NXT TV on 4/5.
