Hi All,
I just called the Admissions office of Johnson and had the following conversation with them (verbatim):
"
Me: Hi, there are rumors floating around that Johnson is already rolling out their decisions for R1 applications. I'd like to confirm if that is the case.
Admission : Our decision notification is Dec 20th.
Me: Does that mean that we will not get the decision before that?
Admission: Yes
"
I think that clears it up. So, we can all breathe a sigh of relief and postpone this excitement/anxiety for a few more days.
If this information helped, kudos are welcome

While I don't doubt that you did have this conversation, my friend did indeed get an admit call yesterday, I'm just reporting what I heard, do with it what you want.
