Relax this is a speculation thread right? For me that is more realistic than 9 tf machine everybody thinks of. This because you think Sony wants to sell at 399, fom me they gonna sell at 599/699. Ever Seen apple or Samsung selling at cheap price? Sony is no more ps3 sony, is ps4 Sony, they can go higher, plus inflaction. Realistically you can't manage ray tracing and 8k with 9tf,Cerny itself said 8tf is the bare minimum for 4k (at ps4 graphic level) to achieve new graphic level and 8k they definitely need 13/14tf
