Returning to the question asked by OP, I doubt that there will be many.
JHU should have no trouble meeting their yield this year. I think most colleges and universities that have had negative press on issues regarding student safety–including MIT, UC Santa Barbara, Wesleyan, Hobart & William Smith, Vanderbilt, Georgetown, UVA, U of Oklahoma, etc.–will have no problem continuing to attract very large numbers of qualified students.
