Nonsense,
1. There's only Malaysia set by Sony Malaysia and Imported set ( from other region )
2. Both sets MY or Imported 100% original from Sony, the difference definitely the warranty itself, MY set warranty / repair by Sony Malaysia because they are also a official distributor of PS5 here in Malaysia.. Meanwhile Imported set not eligible for local warranty / repair by Sony Malaysia because the distributor basically a 3rd party company that import the set from other region such as from japan, hongkong, europe etc.
