Its an advantage to be informed early. It allows you to make decisions on R2 applications with enough time to get them done. And if you get an acceptance you have the choice to stop applying.
They must have sent out the first batch of dings today. They claimed they were going out already but no one had heard anything. I wouldn't be surprised if dings go out in groups and acceptances get called daily. I know they pretty much only call during a few hour window a day (may differ for internationals), every acceptance I know came in the 5pm time frame.
I am confident there will be some more admits, there are too many people on here with excellent profiles, and I know from talking to a lot they definitely would put great apps together. Just look at the success getting interviews to schools like Chicago...gmatclub has a far higher success rate than any other site I have found.
Any R2 people that need help with Kellogg apps let me know, I will gladly give you any help I can (as long as its not proofreading). Since its my only acceptance so far its obviously the application I did that I have the most confidence in.
