I have been looking for one as well...from my research so far, the G9 is a great all round camera, but the lens is not exceptional (i think the G6/G7 lens is sharper). If you want to compare GX 100 vs G9 (both are zooms) - i think G9 is a better buy....
The fixed lens P&S on the ohter hand, (GRD II) seems to be very interesting...its about $700 bucks...a bit too steep...maybe, the GRD will soon be discounted soon or keep looking for a good used one...
anyways - i wonder why Tier 1 manufacturers just dont take the hint and make a good P&S with great lens....(like the GRD). The DP1 seems to be too far off and i have doubts about the manufacturer...
Leica and Panasonic make one as well...but they are even more expensive!
