New Birds Of Canada Issue

In the latest issue of Canadian Stamp News on page 11 there are pictures of people from the Royal 2017 at Boucherville. One of the pictures shows Canada Post Stamp Advisory Committee member Liz Wong "unveiling the latest Birds of Canada set of five stamps."

The images of the stamps are definitely not last year's set.

I can't find anything in Canada Post's web shop and, of course, have not received a Details announcing the new set.

Anybody hear anything about them yet?

The RPSC lists them as being issued on August 1.

Perhaps unveiling them this early - almost a month and a half - indicates that the issue date has been changed?
