The discount of the game in the USA by Stern and/or its agents SHOULD mean the price in Australia should also come down.
It's like anything brand spanking new, the first people to buy always pay the most. Always best to wait for the dust to settle and get a better price at a later date.
Cars in Australia are a classic example, when the latest model Camry was released it was $30,990, now it's $26,490 with extras added. People who pay the high price must get pissed 3 months later when they see the price drop so much......
