Look at us F3 owners, not even 2 years later and the F5 replaces it with the codec F3 owners wanted and 4k they don't want but will have to pay $4000-$5000 over F3 list price.
Life is risk. Fundamentally, however, you should make decisions in the present. When I bought my F3 the technical specs and future functionality was clearly explained, and at no point did Sony ever promise me "we won't put out a superseding model in less than X years."
Some people like to cry over spilled milk.
