From a more practical standpoint, what impact will the 850 have? It really is a bit of a game shifter. Certainly it won't obsolete the Canons (rolling my eyes at the idiocy of that statement), however I am hoping it will help drive down prices faster than Canon would want. Also hopefully Canon will make sure that future products don't hold back as they have tended to do the last few years. What are your thoughts on that?
