In short, no. Don't look for hidden messages in the timing of the final applicaiton decision. By the end of the application process, the application committee is anything but organized, and they just have a long list of names to call/email with the final answer, which is split up randomly between several people, who each do their job in their own pace…
For instance, I had probably been the last person to receive an email advising me that I will interview with INSEAD (Friday afternoon on the week of announcements), but was one of the first people to get a call that I was admitted (on Monday morning)… Call vs. email, Friday vs. Monday – there are no rules! 
All the best!
