It's most probably the new Silent Hill. I really think Pes 2021 will just be an update because of many reasons:
Covid19 and the difficulties coming from working at home (they had to close offices because several Konami employees had coronavirus), new gen transition when Konami has always struggled with Pes, new engine for next year so they think it's better to focus on that.
The pandemic began in March, atleast people began to work from home around then. I think it's a weird decision to back off with the new engine, better to release the game early 2021 than a fucking DLC.
