I'm not aware of anything - seems like there would have been an announcement by now if something is in the works.
Wicked Wind Down is usually offered on Tuesdays (7/4 is a Tuesday). Why not call MS and see if you can book that for July 4? WWD has a reserved spot on the deck to see the fireworks and It's not crowded. Other space on the deck (available without reservations on a FCFS basis) can be.
We enjoyed this event when we booked it last November.
