Agreed its good to think positive, skepticism is not always useful, they may have a good reason to extend, such as relaxed visa rules for non-EU students etc. Additionally, they do have rolling admissions process, which allows them to keep the slate clean and accommodate more applicants until the deadline. Regardless, I think that RSM not a bad choice, if you're post-MBA plans don't involve Finance or Strategy(specifically, I-banking, PE, Ivest Mgt, VC or Mgt consulting)

Safety School(s) : Emory (R2). Previously, RSM was my safety, but now I am leaning towards Judge (Cambridge). Good luck with your applications.
