no point getting those imported set due to warranty issue , however incase anything you can send it for repair locally ( at some of gameshop / 3rd party technician that provide repair for PS5 console / controller ) .. but it's up to the buyers , if they fine with it , go for it 

Imagine PS5 Malaysia set got 1 year + 90 days warranty , you can even extend your warranty ( 1 year additional ) , total would be 2 years + 90 days , fully covered by Sony Malaysia 

Imagine PS5 Imported set , lets say Japan set .. Some seller didn't even dare enough to give warranty and Some seller might say supplier warranty .. For supplier warranty i've got no idea how it works .. Either they will help you to send the unit to Sony Japan with some minimal charges ( * might take a long time for this matter ) or they will try to fix it by their own in house technician .. It's quite a hassle in the future 

In the end , it's your money and you choose
