Dcool - here is a link to the Borse Berlin Exchange "Filings" page. You'll can see that PGI is listed, but as I noted a few days ago, there currently is no date of listing.
I have an email out to an address specific to new filings to see if I can get any information as to the status of the filing and perhaps a target date for listing. If/when I get a response, I'll share here.
