Am wanting to upgrade camera (currently using Canon SD600). Any thoughts on the Canon G10 vs new Canon G11?

A major difference between the G10 and the G11 is megapixels. The G10 is 15 and G11 is 10.
It may not seem important but for cropping purposes it is. If you are one of those people like me who crops almost every underwater photo I shoot megapixels are of major importance.
Consider the comparison of the 10 MP Rebel XS and the G10 here

At ISO 100 the G10 is doing very well, but by ISO 400

the larger sensor with fewer MP is much better than the G10.
I'm aware that the G11 has the same size sensor as the G11 and the results may not be that big a difference, but the point is that 15 MP isn't very important if the camera is not up to it in any but the best situations.
I'm no camera expert but my guess is Canon went with a lower MP on the G11 over the G10 to accommodate higher ISO for lower light conditions. No doubt Canon did that for land use purposes.
