According to the Pentax Forums, this is the new K-series DSLR that will be officially announced on May 20th. If authentic, the image - which names the camera the Pentax K7D - suggests the DSLR has a 14.6-megapixel sensor, as with the Pentax K20D, but paired with the PRIME II imaging engine.
There's also said to be support for HD video recording, a first for Pentax in an DSLR, together with a viewfinder offering 100-percent coverage. Other features include image stabilization, dust removal and resistance to dust and water.
Around the back there's said to be a 3-inch 920,000 preview LCD with live-view. Connections would include HDMI. No word on pricing however, though.
