OMG..
The PS4 20th Anniversary Edition is DELAYED 3 months for my country :/
and Sony in my country basically just say "we're sorry, please be patient" in the official letter. I wonder... Do Sony Asia know about thus brouhaha.... O_O
1. the winners need to pay 200 dollar extra for it to Sony
2. It delayed 3 months
Like Shifty just wrote, it could be a scam.
Are you sure the email address that sent you the whole "right to buy the PS4" notification is from a genuine Sony domain name? Be sure to check the real email address and not the sender indicated by your email software.
