I'd say yes for all of them except KZ3. It was 5 years between KZ1 and KZ 2, which points to another 5 years for KZ3, or 2014. If the PS3 is still the flagship sony console in 2014, well, Sony has some big problems. (Wii Too w/ PS3 graphics and next gen motion controls, Xbox 720 with Natal 2 would utterly destroy the PS3 w/ Arc. Not a fanboy, it's just a fact)
Wii has more 20 million sellers than PS3 has 5 million sellers.
