I can see not wanting to upgrade but why is a faster lens with faster autofocus a bad thing and how is this going to kill the G15? This forum seems to attract a lot of people who just want to vent their frustrations if the latest offering is not for them.
For real. If you have some irrational dislike of larger apertures great, get yourself a damn superzoom bridge camera and be done with it. The whole reason they have these P&S with more modest zoom lengths of 3x-5x is so you can have a larger maximum aperture throughout the range. The presumption that making these lenses faster will harm their sales (if that's what is meant by "killed the G15"), is insane. That was half the draw in the first place.
