The Pro Wrestling Insider is live at the tapings and had these notes:
They are set up to tape ECW, as previously reported on the site.
They have a curtain covering the Smackdown set and the small ECW entrance is set up on the right side of the set.
There’s a ring with an ECW logo set up. There are two hard cameras set up where the Smackdown stage is.
Atlas Security at ringside.
There is also a small Titantron screen over the ECW entrance.
