Is three days too late to hear good feedback from a job interview with HR?

I did an interview on Monday, and hr gave positive feedback as his first impression and told me the hiring manager also liked my resume etc. He told me they would provide feedback quickly, it is going to be three days in a couple of hours today, and I still received nothing from their side. Do you think I can still receive good news regarding the next steps in the process?
