The Canon S400 has turned out to be a great success and Canon is not going to change it much. They did make some minor improvements to the movie feature.
Canon has information on their website:
You are probably right about the price. The S400 price has been going down and it will likely be phased out when the S410 shows up at a higher price.
There are lots of new cameras due in the next few months. It will be interesting to see the customer reaction when they can get their hands on them. The reviewers will be kept busy.
It certainly looks like a horsepower race. But instead of horses, it is pixels. Eight megapixels seems to be the high-end target for now.
I've read from the trade shows that Canon is releasing the S410 in April. Based on the Cnet blurb, it looks like the only real difference is the Pictbridge feature? Does anyone use this feature or think it is important? Does anyone know if the S410 will have any other improvements? Canon claims it will retail for 399 - the same retail as the S400, although now you can get an S400 for about 350. I'm assuming that there won't be any discounting of the S410 for a while. thanks in advance
