The three day wait is only for users that recently modified their account.

From http://support.apple.com/kb/HT5570

"As a basic security measure, Apple does not allow two-step verification setup to proceed if any significant changes have recently been made to your account information. Significant changes can include a password reset or new security questions. This waiting period helps Apple ensure that you are the only person accessing or modifying your account. While you are in this waiting period, you can continue using your account as usual with all Apple services and stores."

The process forced me to update my password to use their new password requirements which then forced me to wait 3 days. I'm pretty sure my old password was secure but it didn't meet all of the new standards. Kind of annoying.

I was not prompted to update my password (and had long ago set up security questions), and was able to set up 2-factor immediately.

Your password must have already met their new "security requirements", mine did not.
