EAD Expedite Email

I just called the SR and requested my EAD expedite process. Two days later, I received the email as follows:

The status of this service request is:

Documentation submitted meets the requirements for expedite processing of your application/petition. You should receive a decision within 60 days.

Does anybody know how long is going to wait for the approval?
Please share your experience here. Appreciated!
