Kinetics says this is a GH3 underwater case??? Only a marketing trick?

A couple of readers sent me a link to that image. It is coming from the Nauticam Europe Wholeslae store. On the image and within the text specification you can read many times GH-3. So what the heck is that? A huge error? Or…they know the GH3 is coming soon?
I think this is probably a marketing trick to promote the [shoplink 30926 ebay]Gibson Underwater Housing by BS Kinetics (for sale here on eBay)[/shoplink].
