Apple website Apple Gazette is
reporting rumouring that Leopard will come with an all-new interface, supposedly with lots of black glossy things (similar to Vista, indeed): “Apple Gazette has received a tip from an apple insider that the Mac OS Aqua User Interface will be replaced with a new UI named Illuminous. The source goes on to say that we will see a demonstration of Illuminous at Macworld 2007.” I have never heard of this website, so I cannot make an assessment of its reliability, but suffices to say that it is highly debatable. Interesting nonetheless. Update: More info.
