Let me put it this way: what is the difference from a thicker AA filter? You know what that does right?
Phil himself said in his review (page 17) "in-camera Bayer interpolation algorithms", which means that it can be altered with a tweaking of the firmware. It does not need to "conceal a problem".
You do know that both AA and the "in-camera Bayer interpolation algorithms" are working in your 300D right?
The AA filter is in the analog domain, while the Bayer Interpolation filter is in the digital domain.
The Moire is produced when going from Analog to Digital domain (Sampling Theorem).
The in-camera Bayer interpolation problem that Phil talks about is the one that makes Moire appear as Mazes in the in-camera JPEG shots.
So
- yes: this funny mazes can be solved by a FW update (and probably will be, although one has to go to the Nikon Customer service for that).
- no, the moire is not going to disapear with a FW update.
The problem with the 300D stonger AA filter is that I may not be able to go up to resolution N, because it filters strongly from N-1.
The advantage of the AA filter in the D70 is that it filters slowly from N so that it can get good detail at N.
The problem is that if in the subject there is also detail at N+1, N+3, etc, this will show as N-1, N-2 on your picture, hence the moire.
Whether one prefers to loose a bit of sharpness, or to do post-processing when moire appears is up to the photographer.
I prefer to loose a bit of sharpness, rather than taking the risk to find a moired picture (it's the ame reason why I shoot raw).
