Captureintegration got the scoop on a new H4X body that briefly appeared on Hasselblad's website:
"The H4X provides a fantastic successor or upgrade to your H1 or H2/H2F body and supports all H System lenses, most third party backs*, and even features a film back option. The H4X also provides a technological bridge to our faithful H1 and H2/H2F customers enabling them to take advantage of all the features that photographers have come to expect from a Hasselblad H4 series camera, including Hasselblad’s world-acclaimed True Focus technology, which allows you to concentrate completely on creativity without worrying about focus mechanics, and the ability to use the HVD 90x viewfinder optimized for the 36×48mm format."
