The Pentax 645 digital camera that has cropped up in prototype form at many photography shows over the years looks like it may finally see a release next year.

According to an official press release on Pentax's Japanese website, the medium-format DSLR has been scheduled for release in 2010 alongside the smc Pentax-D FA645 55m F2.8 lens.

The website tells us the 645 digital will feature an image sensor of "30 megapixels or more", but otherwise, specs are thin on the ground.

We'll bring you more details on this when we have it.
