Best to compare (Pardon me) apples to apples, since while the exchange rate is about equal, Australian prices are higher than US prices.
Current Base 21" AU$1,399 new price $1,349 (save $50)
Current Top 21" AU$1,698 new price $1,689 (save $9? Probably a typo on 9to5mac's chart)
Current Base 27" AU$1,949 new price $1,999 ($50 more)
Current Top 27" AU$2,299 new price $2,499 ($200 more!)
Those prices may shift depending on the region, but I'd say the difference for the US systems will probably be similar: $50 less for the low end, $200 more for the high end.)
All the MB Airs except the base model are $100 cheaper, the base is the same price. (probably from SSD price drops)
The Macbook Pros are both more expensive than the current 15" models, which might mean those Retina Display 15" models.
Finally the base Mac Pro is the same, and the "Ultimate" is the same price as the server config. The "Best" model could be cheaper or more expensive, depending on whether that's an 8 core or a 12 core model.
So pretty much what I'd expect from a Mac update. I'm very curious what that $200 price bump n the 27" might mean.
