I know that there are many "no AA filter" (K-5 IIs) fans here, but I hope that either
a) there will be an option with a Bayer-AA filter, or
b) they will leave the RAW files untouched.
There was talk of a "software AA filter". Obviously, the latter tries to come to the rescue when the damage has happened already, so I'm hoping it is only something to polish JPGs out of the camera, but the RAW data is left alone.
If they are messing with the RAW files, that would be bad, AFAIC.
As far as RAW files are concerned, I don't think any processing -- whether it is noise reduction, moiré removal, or other artefact suppression should be baked into (not so raw anymore) RAW files. If all these issues are dealt with outside the camera, one will be able to benefit from improving algorithms over time.
One approach to address the absence of a Bayer-AA filter is of course the "sensor shift" technique that has been discussed elsewhere. But this will work for certain shots only, so it is not a general remedy and it isn't a strict "software" solution either.
Overall, though, the K-3 sounds very promising and perhaps we haven't heard everything yet.
