They have the body only (silver) in stock at B&H for $649, so it's not that big of a stretch from the high end of your target price range. I agree though, $499 and they would be a hot little item. I'd probably buy one right now, but the current price leaves me on the fence looking at other options. I'd like to have something lightweight to take snowshoeing this winter and the weather sealing of the OM-D is appealing, but then the price starts going up from there and I don't want to be balls deep into a system that's likely to decrease in value come early 2013, which is just around the corner. I wish that other thread didn't get shut down from all the RAW ranting, it was starting off quite helpful.
That is a pretty good price, better than I've seen listed elsewhere which was usually $699, and frankly when your spending $700, you don't really appeal to entry level first time buyers, and there are lots of other cameras for only slightly more like the NEX6
As far as systems go, I think the body could perhaps be a bit outdated quickly, but the glass should certainly keep its value. Lenses like the 25 1.4, 12 f2.0, 45mm f1.8 etc are always going to be popular and you'll lose little if any if you sell them.
