Sony might introduce PlayStation 4.5 for VR and 4K
You know that Sony introduced slim models few years after the introduction of their console. And, we know that we are going to see slim model in next few years, but there might be another PS4 called Playstation 4.5.
Okay, consoles are not the powerful devices for gaming but I wish they were more powerful. Besides of having no support for 4K, in most of the games, you cannot even get 1080p. Cough* Cough* Xbox One Couch* Cough*. And, now VR is coming which requires 120fps, if you do not want to get motion sickness. Even though Playstation VR can provide 120 fps, I cannot say that its graphics are awesome, as you might expect. That is why it looks like Sony will introduce more powerful Playstation. Even though we do not have any details about how powerful it is going to be, rumors indicates it will be for VR and 4K.
