Sony has yet to announce a reveal date for the PlayStation 5 and now a popular gaming YouTuber has claimed that there are supply chain issues that have forced the company to delay both the reveal date and the launch date. However, PS5 fans have been remaining optimistic about their choice of next-gen console, with many hoping for 13 teraflops of GPU performance.

If they had 13 Tflops they would have been quick to announce that. Almost every insider that has leaked info has suggested a more realistic 9.3 Tflop figure. My guess is that Sony is going for the cheaper console and leaning on their exclusives instead of horsepower.
