I do not believe anybody here has so much analyst background to prognose accurately which technology will prevail in the future. And that's because that's not a technical decision but a whole different matter. Like VHS/Beta and others. With complex technologies and big corporations, everything can change.
I do not think battery power makes the big difference now, the new nikons can rung a long time on one battery, I think it's about the same like yours D60, Cotty. At least these I shot with were. Personally, I don't care whether it's CMOS/CCD/LBCAST/ETC... but how it shoots nad how it controls. I am not a prognosist, and frankly, I totally don't care. If I were debating whatever is a little bit better, I wouldn't shoot any pictures :-) I just shot some great shots with Leica and its super-sharp lens on 10 years old HP5+, which indeed is bit fogged. Did I mind :) ? Frantisek
