Don't know how much viewing this post still has, but I got myself an Oly OM D EM-5 the other day. I also made a smart move and got a printed copy of the user manual. I was uncertain about the camera at first, but after I had perused the manual, I like the camera. It reminds me so much of a smaller version of my Nikon FM that I find myself reaching for the film advance lever! Picture quality is very good, but the 14-45mm lens is a little soft on the long end, but still very useable. The wide end is very sharp. I find the menu and controls to very quirky compared to my Nikons, but I am getting the hang of it. I wish I had more choices to set the function buttons, as I still have to go into the menu to make some settings that are much easier on my D90 and D300. I like the Oly a lot more than the Nikon V1 I had and returned. I have to save for a few more lenses to get to a fairly light and compact DSLR outfit for the times when my Nikons are too big and heavy. However, I don't see the Oly replacing my Nikons. I like where there are constantly new lenses coming out for the 4/3 format, which is good (more choice) and bad (have to resist the urge to want them). I wish Nikon had gotten on the 4/3 bandwagon instead of their own format. That decision will probably limit their sales, as the lens choices are likely to be only those made by Nikon.
