You can see this behaviour on the attached screen shot. Note that I have a number of pending updates from proposed (top left). Note that I only have installation of security updates enabled, I do not have 'Download all updates in the background' set (top right). Dispite this I already have the updates in my apt-cache, and no downloads will be required before installation (bottom right). This seems wrong and definatly a change from Intrepid.
