On October 29, the Commission on Presidential Debates said it won’t change the 15% poll rule that it has used throughout this century. Here is the announcement. Although the decision was made on October 28, it was not announced until October 29.
Two lawsuits are pending against the 15% rule, both in U.S. District Court in Washington, D.C. They are Level the Playing Field v Federal Election Commission, and Johnson v Commission on Presidential Debates. The first one depends on campaign finance law and the second on antitrust law.
