Well, Imaging-Resource has posted a really nice hands on article with a thorough geek lovers investigation into the new switchable Pentax LPF/AA filter technology:
"During the exposure, the anti-shake actuators oscillate the sensor assembly in either a circular or linear pattern, shifting back and forth a pixel or less in each direction. It thus does pretty much exactly what a conventional LPF system does, but without all the optical complexity -- and it can be turned on or off at will."
It seems amazing this can be controlled down to the pixel level.
"Bottom line. It's not often that we label an imaging technology "revolutionary", but if ever one deserved to be called such, this is it. It's a fundamentally different approach to anti-aliasing, and one that appears to have surprisingly few downsides associated with it. For the first time ever, there's a camera on the market that lets the end-user decide when they want a low-pass filter, and when they don't, with little apparent penalty regardless of their choice. And it was Pentax that brought it to us."
