Deferred or Not

I submitted MSU application 2 weeks ago. My act is 24 and weighted GPA is 3.99. Today, I saw my application status, and it said,

"Thank you for your patience and continued interest in Michigan State University. An initial review of your application indicates you are a competitive applicant to MSU. Due to an increase in the quantity and quality of freshman applications, the Office of Admissions requires additional time to thoroughly review all applicants before making a final decision.

Admissions decisions will be released on a rolling basis, beginning in mid-October 2016. You will receive a decision on the status of your application on or before March 17, 2017.

No additional documents are required. The most up-to-date information will be posted to your account as soon as it becomes available. Students will be notified by email when a change occurs on your account.

Thank you again for your patience."

Is that mean I got deferment or I need to wait more?

It means they are going through the applications. It means you have to wait, that even though they have rolling admissions, they are promising a certain date. You must roll with all the other applications.
