Sony has been talking about releasing a new PS4 model that is to contain better hardware and use the x86 hardware that is in the PS4 to good use. Sony Computer Entertainment executive Masayasu Ito said that it is just talk, and not a confirmation of a new PlayStation 4 model.
Anyway, with a interview with Masayasu and 4Gamer, a PlayStation gaming publication in Japan, 4Gamer asked him if a new PlayStation with better hardware is on the way to ensure PlayStation still has that "Best Performing console," he responded with a potential to make a new PlayStation 4 Model with better hardware to use the x86 chip inside the PlayStation 4, however, is not on the board with the idea, and believes it can separate the PlayStation community. Many PlayStation fans believe that if Sony does this, it would be like Nintendo with the 3DS, you can't play 3DS games on older Nintendo DS's. However, Sony said it is not on the top of the list, but something to consider.
In my opinion, releasing a beefy new PS4 model that you have to buy games for and for a much higher price, it would be like a PS4.5. The 8th generation is still going on, and we don't really this, I think Sony should focus on a PS5 or a other new console, not a PS4.5.
