Yes, the difference in dimensions have been noted, as I said. They can
still be the "same" sensor. Not like it's rocket science to arrange pixels
from 30x45 to 33x44 :-) The more interesting question is whether S2 has
microlens etc. that would make it better even using the same generation of
technology.
