The following message comes from Madman in Australia:
Please note that due to circumstances beyond our control the PONYO BLU-RAY scheduled for December 29th is canceled. Furthermore, the PONYO DVD is now a single-disc DVD product and remains scheduled for release December 29th. We thank you for your ongoing custom and apologise for any inconvenience these changes cause.
One common theory why the North American Ponyo BD was delayed was to give an exclusive window to Japan. Region-free players and discs make the home markets more vulnerable to imports than ever, and when you consider the high retail prices for Blr-Rays, this makes sense. If this is so, I would expect to see Ponyo in Australia about the same time as the Americans.
In any event, this is a very hard blow for fans. Whatever the reasons, everyone had their heart set on Ponyo for Christmas. That's a real shame. Somebody in the corporate food chain seriously FUBAR'd.
