这封邮件是啥意思？预定offer?

"My name is Dr. XXX and I am the Director of the PhD Program in XXX. This email serves to notify you that your application to the program with concentration in XXX has now passed our two level review and I am happy to inform you that you have been shortlisted as a priority candidate to the program. A formal response letter will be coming your way by email no later than Friday February 8, 2019. "
这算预定offer了么？还是最后告诉我来个拒信？
难受。。。
