Everyone that's repeating the same stuff over and over and not reading the posts? Freaking stop it! If you're going to rant at least add something of merit. They know it's an issue. We can yell and scream all we want but it's going to do us no good. We just have to wait.
Also, being a tech guy myself, I can almost assure you that it's probably due to flooding as a few others have pointed out. This is a big ticket item, a lot of people want it so there's probably thousands of purchases rolling in for it. I hope it is as simple as that or a region coding issue.
If it goes on longer than a few hours or even into tomorrow there will be reason to complain but for the moment? Amuse yourselves with this:
