Sony (erroneously?) listed as Medium/Large format exhibitor

The PhotoPlus website listed Sony within the Medium and Large format category too. There were some rumors saying Sony could produce a medium format sensor for other companies (like Hasselblad). But this isn’t a rumor from my trusted sources and that’s why I wouldn’t give it too much attention for now. Don’t dream about a digital [shoplink 21165 ebay]Hasselblad 503cw[/shoplink] liek I am doing :)  Could be a simple error too! May some source can enlighten me a bit on that?

UPDATE: Also Nikon is listed there. And according to patents they are indeed working on a medium format camera (Source: PetaPixel). And they alreayd made lenses for Bronica and Plaubel Makina medium format cameras.
