Just reposting this here for spreading news. Apparently there are already reports of bricked PS5 consoles due to a bug that corrupts the internal storage and makes the console unable to boot up. Some reports claims this may be tied to Rest Mode, so disabling it --may-- help reduce the chances of the issue happening. Also it seems that the issue already happened to some Youtubers who received preview units.
I don't have any way to check any of this other than random news on the web.... Anyway, take care if you planned to buy a PS5 now.
