New camera?

I see that Pentax have now released further details of their hotly anticipated full frame DSLR camera.  Apparently, Ricoh - the owners of Pentax - have formed a partnership with Lytro - developers of the "light field" technology, and they have incorporated this technology into their new "Pentax Lytro" camera.  This means that photographers will never need to focus their pictures on this camera as this can be done in post-production, choosing which part of the picture is in focus, and how much is in focus (ie depth of field) - just like the Lytro cameras already on sale.  This removes the need to choose an aperture appropriate to the required depth of field.

I understand that in another technological innovation, Pentax have also developed "shutter field" technology, which means that the shutter speed can also be adjusted in post processing,  I can see that this will be an enormous benefit to photographers who are photographing movement.  No longer will you have to decide whether to use a fast shutter speed to freeze the motion of waterfalls and rivers, or a slow shutter speed to produce that milky flow look:  this will, in future, all be controlled in post processing. It may also allow emulation of 10-stop ND filters ("big stoppers"), which saves on buying that expensive piece of glassware.

Sounds like some really interesting functionality in a full frame, high resolution SLR with that trendy "retro" look.

The only thing I don't understand is why they didn't launch this amazing camera at the Photography Show a couple of weeks ago.  Why wait until April 1st?
