If the PlayStation 4.5 is going to run the same games at a higher visual fidelity and a higher framerate, but still use the same user interface and store, why should I get it? The leaked document is stating that Sony doesn't intend to split the user base, but I find that hard to believe. I can see a future where each new game will have a sticker on it stating, "Better with Neo!".
My guess is this superior PlayStation 4, which will support 4K, will be the best way to play games moving forward. Just like Apple and their yearly releases of a slightly improved iPhone, Sony has learned that everyone wants new and better and they plan to give it to us.
This is exactly what gamers need and Sony has been preparing for this ever since they decided to make the PS4 a PC based console. They have the ability to incrementally upgrade their system to give us a better console. This a borderline genius. If you have a PC it's up to you to make upgrades on your mobo, CPU and RAM. Which a lot of people like to do and a lot more people don't like to do. With this move Sony is able to control the upgrade cycle, prolong the life of the PS4 and make millions of dollars. We all fell for it hook, line and sinker and now we have to pay.
It's time to sell, sell, sell!!! Don't get left behind. The future is coming and will probably be announced at Tokyo Game Show or E3 this year.
