With WBD possibly losing the NBA, it's not going to bode well for an AEW deal. I think they will sign AEW to a new deal but I expect the deal to be well below what it would have been had WBD retained the NBA rights.
The NBA and other programs on Turner networks are like sharks that AEW attached itself to like a remora. AEW ate well off the scraps those programs left, but with the great white shark (NBA) no longer swimming in Turner waters, no the remora will be left to fend for its self and I don't see it pulling in the numbers (ratings wise) for WBD to strike a deal beneficial to AEW.
In short, AEW doesn't have bargaining power and WBD will be in cost saving mode. I expect massive cuts coming AEW's way in the near future.
