According to Spectrum Sports 360's Jon Alba, WWE has an agreement with the city of Orlando, Florida, to run shows at the Amway Center through October 30th with no fans in the building.
Alba tweeted that he spoke with a city rep who gave him the details and that barring any amendment, WWE will be able to run empty arena shows there for the next two-and-a-half months. On Friday, Alba posted video of WWE trucks preparing to load equipment into the arena, further confirmation that the company will be kicking off a residency of sorts starting with next Sunday's SummerSlam.
As has been discussed and reported here, WWE has been looking to get out of the Performance Center due to the environment, wanting a new look for Raw, SmackDown, and pay-per-view events. Nearly in concert with the move, WWE will be going live with both Raw and SmackDown, starting with next Friday's go-home show for SummerSlam. Their hope is the changes will help turn around declining viewership.
None of the above has been announced by WWE as of this writing.
