Sikorsky is going through a change in ownership, and the S97 project is internally funded. So it would not seem unusual for the project to be idled until the business situation at Sikorsky is all ironed out.
Sikorsky also has its hands full getting the SB-1 flight demonstrator ready for testing by mid-2017. They are under contract to fly this JMR aircraft, so it would have priority over the S97 project.
