Defkalion Green Technologies has compiled a list of articles from Greek numerous newspapers covering the Rossi/E-Cat/Defkalion story. From the photographs in the articles, many of them appear to be reports from the Defkalion GT press conference held in June.
Unfortunately for non-Greek readers there are no translations provided, and since the articles are in PDF format, Google Translate is of no help!
Links to the articles can be found here.
