Everything seems the same as the S300 and S110, respectivly, except that they now have up to a 400ISO abiltiy(I THINK they used to only go to 100). I'd wait and check how these affect the market, you might be able to geta steal on the s110 once it's "officially" discontinued.
Also, I didn't get to see a mention of any sizes on these. If they shrunk the S330 down to the S100 size, it would be a GREAT camera.
