There has been no movement on the final four for summer of fun. Those strikes will likely never see the light of day. I think the old program left such a bad feeling at Flamingo/O'Shea's that they just want to move on. Remember, the person with the final say at Flamingo/O'Shea's is the person who put the strikes in Paris and the new strikes at Ballys. That person is now in charge of strikes at all four of the PPE group mentioned in this post.
Don't know when the machines will be going in at O'Shea's and Flamingo hasn't been finally approved yet.
