It's been reiterated a dozen or so times now, but Sony has clarified that the PlayStation 4K (or Neo as it's known internally) will not bring a premature end to the current generation. Speaking with a Russian website, Worldwide Studios president Shuhei Yoshida explained that "PS4 is still PS4". He continued: "The new high end PS4 is still PS4, so the lifecycle is not going to be shorter."
It seems that some fans are still wrestling with the idea of what the PS4K is, so let's spell it out one last time: it's a PS4 that will play all PS4 games better. There'll be no exclusives for it, and software will still be developed with the existing model in mind – you'll just get better performance and enhanced visual fidelity if you own a PS4K.
The confusion is beginning to cause Sony some headaches, especially with Microsoft spouting its plans so early. The platform holder has indicated that it wants to announce its new high-end hardware and release it almost immediately, with a launch later this year extremely likely. Hopefully the information comes sooner rather than later, eh?
