In digital world, special finders are replaced with live view - even extermal monitors. I really prefer my F5 to my F6 because of interchangeable finders (I have and use all of them). But I understand that Nikon would never sell enough finders for F6 to pay for R&D - this camera was NOT targeted to professionals and media companies with high budgets. IMHO F6 is F200 in fact - yes much better built, just like D200 in comparison to D100.
