I am baffled that so many people in here seem to think Sony is going to abandon the 40 million PS4 owners, give them the finger, and shift focus so quickly away from one of the most successful products they have ever launched and literally one of the only highlights of the company, profit wise, over the last few years. Makes no sense that they would do this. So much doom and gloom.
A ps4.5, executed correctly, would be great for everyone.
Its more about not trusting 3rd parties to make games that still perform adequately on vanilla PS4 rather the the platform holder I'd say.
