According to Apple Insider, the new version of OS X coming to us sometime next year will have a Finder completely redone in Cocoa. Traditionally the Finder was done in Carbon and will finally get a revamp to the new code-base platform. This could bring speed and extra nicety to the finder for all who enjoy the quality of their Mac.
The new version of Leopard will also include Image Boot. This feature has the ability to let you put a copy of the OS onto another hard drive or partition on your internal hard drive and allows you to boot from it.
What else could Apple have for us in January as they have almost exhausted all of their products in the past year or so.
