I see a slight difference, but honestly, I feel they could have done more. Most of the pictures people are posting in the pictures/videos thread are one of the following:
1. resized. simply resizing it to a smaller size creates the image to look sharper.
2. edited. some are so highly edited, any picture can look better when edited.
3. up close. pre/post portico, the lumia has never had a problem with shots taken up close.
my continuing gripe is when taking pictures outdoors..where there are branches, grass, leaves, etc in the picture...they continue to look very soft.
