They are not new. They are not produced by Quality Chess. (Did you see "(Please note that this volume is produced with the assistance of Quality Chess, but is not a Quality Chess product.)" on the page?.
In fact, it looks like the magazine hasn't come out in more than two years.
At any rate, you can buy them for less than half that 33 Euro price directly from the publisher: http://chess-evolution.com/.
The magazines are listed on: http://chess-evolution.com/index.php?route=product/category&path=37&sort=p.model&order=DESC
This is new magazine from Quality Chess. Has anyone had a chance to read it? It seems to be a user friendly kind of Chess Informant. I am thinking of buying one to see how it is.
Here is one issue:
