In Europe there are so many little online shops that I couldnt possibly keep tabs on where the E-P1 is in stock. But finally redcoon (one of the biggest european online shops) is taking preorders in some countries. And depending on the country you live in the E-P1 is in stock or available for preorder only.
Check it for yourself!
P.S.: I am working on a MicroFourThirds adapter table similar to the E-P1 table on the top of the page. Should be online tomorrow.
