Oly tied w Nikon?

How does that change what the best camera is , the best at anything is seldom the most popular in the sales charts , I should imagine they will sell a lot more Ford Fiestas than Aston Martins . The 6D will compete with the D600 in the low priced FF market, not the D800 which is a more specialist camera. Overall very few folk would consider spending a £999 on an E-M5 so by your logic that would make a low end p&s or a mobile phone camera which will sell far far more than nay interchangeable camera from anyone. You are aware that Nikon were the only camera company making any profit in the recent sales numbers.
