I hope Fuji has thought more about their users with the S3. We use several S2's, and both image quality and mechanical features are fine for our needs. However, the small buffer and failure to generate thumbnails for LCD review can be really problematic. If those issues aren't addressed in the S3, there is no point in laying out several thousand dollars for a slight gain in image quality. Instead I'll buy more S2's now that they are cheap, and wait through a few more marketing cycles beforee replacing them.
It's time for all of us to get past the sensor semantics game and return to shooting. If all the manufacturers realize we aren't listening to their blather, perhaps they will start listening to us!
