According to Benjamin Kanarek there will be two new Pentax DSLRs announced in Paris this fall. Apparently neither of them are the 645D, but one can certainly dream.

I’m not sure how many PMA’s you can show a camera at before releasing it, but Pentax seems to be trying for a record. They are going to be showing the 645D again this year, but again with no release dates. I understand the desire to make sure all the bugs are worked out, but this seems to be dragging on forever. I think the market is ripe for a low cost medium format system, much the same way the Canon digital Rebel revolutionized the digital SLR segment.

It looks like my dreams have been dashed already. According to an interview in swiss magazine photointern the Pentax 645D is being delayed in favor of other DSLRs.

On the bright side, there could be some updates to the existing Pentax DSLR lineup as well as a new body.

“E-410. I think this will be what the E-400 was supposed to be. Grossly
the same as the E-400 but with Live preview (don’t know about A and/or
B)
E-510. Follow up of the E-500 Live preview and in-body image
stabilisation
E-x. Finally. Unknow if this will be at PMA to view or even handle.
Available from july/august. Faster AF, More AF points (maybe 12-14), 5-6
fps and larger buffer. Live preview with more robust screen. in-body
Image stabilisation. at least 10mpix. Different sensor than that of the
E-400 however. Nothing known about noise or body size. Would be nice if
the size stays the same. E-1 handling will be continued in this body.”

This isn’t so much a rumor as a wish, but I’m hoping Pentax will give us some more information on the previously announced 645d. I’m curious about the upgradeable sensor, will this be a user replaceable part? I’m also not sure what the recent merger with Hoya means for the 645d, hopefully it hasn’t been scrapped.
