From what I've read, the ute will at least get a restyled nose. Not sure how much else will change. I haven't heard anything about the station wagon yet. The changes to the Caprice will be more subtle. The VF won't go on sale until mid-year and the other models won't be revealed for a few more months.
For a long time now Holden and Ford have gotten away with making ill-equipped cars and offering very little as standard, while relying on Australians' fanatical Holden vs Ford brand-loyalty to get away with it. Holden only started including air-conditioning as standard on entry-level Commodores about five years ago. Before then it was an expensive optional extra. That is ridiculous in a country with a climate like ours. Despite this, in the late 90's, one tenth of all new cars sold in Australia were Commodores. Sales have plummeted in recent years and it looks like Holden have finally got the message. They referred to this new model today as the "no excuses" Commodore. It has to be able to compete on its merits, so they are including a higher level of technology than they have previously.
