Geez....I can see now that my upgrade path is going to change down the road! Thing that bothers me with KM going to Sony is that they use proprietary memory sticks! Who know what else will change! Oh well...just wait and see! Now just got to worry about service/warranty if ever I need it! From the discussion on some other forums....Nikon and Pentax might be impacted as well, since Sony supplies the CCD chips for them.
