What is Olympus doing over there?

Edit Subject

What is going on over at Olympus? For years we've seen some pretty cool stuff happen over at Olympus, but where did all the DSLRs go? They are doing a great job with their PEN series cameras as far as overall design goes. Also, although they don't get much credit for this, the build quaility on that mirrorless line is excellent. I thought Nikon's J1 was gonna fall apart in my hand. However, there are a lot of Olympus professional photographers that have been asking me the same question. I tool around with them and left Olympus for the Nikon D5100 because they literally had nothing for me. So, for aspiring photographers like myself, that was very happy with my EVOLT E-520, they forced me out! There PEN E-P3 is great for a pocket sized on the go camera (and although the tech reasons you give for ranking it 6th in mirrorless are fair, the build quality isn't really a consideration there and the price point is less than half the Sony NEX-7 ) but it's sad to see them do this. Any thoughts?
