I landed on May 27th, and my ECAS says my PR card was put into processing on August 17 and mailed out on August 24th. Haven't received it yet; hopefully next week.
And FYI, not everyone unfortunately gets ECAS updates about the PR card. It seems completely random who gets them and who doesn't. My ECAS shows PR card application as a separate application below my PR application (it appeared there last week, and now it shows the status as "complete" because the card has been mailed out to me), but I know tons of people who never got a single word on ECAS but eventually received the card in the mail.
