MR on LuLa has a production model X1 for evaluation. He expects to publish his review next week.
I am looking forward to this review and others on the X1. I was impressed with the X1 when I tried it at PhotoPlus. If the image quality and ISO performance is as good as I expect, then I will be getting one.
FWIW, I do think its overpriced, but Leica is in a unique position with the X1. If you want a pocketable APS-C camera with a great lens, then its the only option out there - pay the price or do without.
