You can read about the Canon S500 on the Canon website:
The only news about an S60, comes from wishful thinkers at this time.
I know the S500 is coming out in April but will there be an S60? I have an S50 now. Is it worth getting the S500 for extra portability? I wonder if the image quality should be exactly the same since the S500 uses the same CCD as the S50. If you know any Canon rumors about an upcoming S60, please let me know. Thanks million!
