PhotographyBLOG has posted their GX100 Review. Overall their take was quite positive, citing high ISO noise and price as the two main downsides. Their conclusion ends with following:

"So overall, if you can live with the noisy ISO 400 setting and high price, the Ricoh GX100 is one of the best compact cameras yet for the discerning shutterbug. A real joy to use, quick to respond and offering a veritable treasure trove of advanced features, the GX100 definitely comes highly recommended."
