I did a small test yesterday,pitting my Canon 50D with 18-200 5.6 lens, against my Canon G10. In all my test pictures jpg direct from cameras with just cropping, the G10 had sharper pictures in every picture then my 50D.
Of course it did. All P&S cameras have sharper OOC images than dSLRs. It's the one thing that puzzles those who move from P&S to dSLR.
The 50D was good but the G10 was better. when you enlarged the pictures you could plainly see the sharpness of the G10 beat the 50D.
Sharpness is something that can be (and must be) added to a dSLR image depending on output. That means that if you plan on showing an 850px sample, the 850px sample has to be sharpened appropriately after resizing. Personally I apply the same procedure to my G11 images as well.
So I think the G11 will also be a good choice,and for high ISO pictures it seems to shine over the G10.
The G11 is a great choice. But its choice cannot be justified compared to a dSLR as to OOC image.
(My cameras include 50D, 5D, 40D, and G11, amongst others.)
