Not sure if you have seen the group test stuff from dpreview. Below are links to
Group test for high end and travel p&s. For other group test, just use their search tool and key word "group test".

I think a lot depends on what u intend to use the digital p&s for,,,*
Examples:
1. travel camera - backup or primary
2. Camera u can give to fellow tourist to take a picture of u and your family
3. Digital note taker - use it to scout a location
4. A everyday camera with the level of controls and zoom range u need
5. Does it need to be water proof
On top of that is sensor size versus compactness. Fwiw, pansonic lx3 and lx5 have a slight bigger sensor than the normal one used on most p&s, but still much smaller than what is on the mft cameras.
Personally, I think what u have already is good enough to cover the first three examples, The only reason I can think of for going different would be:
1. Do u need wider than 35 at expense of long end?
2. Do u want better control
3. Faster lens
4. Higher iso capability before noise issues become an issue.
5. Something that is waterproof like the panasonic ts2
Good luck
