You can also go to amazon.co.jp and see the same basic scenario.

You can click "Translate to English" on the top right if you can't read Japanese.
Also, when I checked Tales of Vesperia on launch day, Amazon said it would take 3-5 days to receive, most likely because they sold out and needed to get more stock. Looks like today they finally got some.
The good thing about this is that it sparks more interest in the system for being sold out. More people will want to jump on the hype wagon just like the Wii and Wii fit (although obviously not at those levels). Japanese people love to buy what's popular and they really like to wait in line for stuff.
