Phase I was built with the PILOT model as well, 10 HY (the first tower to rise in Phase I) didn’t have any tenants when it started construction and was essentially being built on spec when it started.
So there’s no reason to believe that they wouldn’t continue with Phase II under the PILOT model simply because they aren’t doing the casino with Wynn anymore. They still need to build the platform to begin construction on 3 of the towers though, the other 3 are on terra firma, though 2 of those 3 are being built above the gateway tunnel casing.
