Briefly: The changes taking place in California Adventure are already starting to be felt. The most noticeable (besides a bunch of construction), is the new 'Paradise Pier' sign on California Screamin'. They have surprisingly disposed of the iconic Mickey ears from the roller coaster, but I do like it. It will help to immerse the guest in the new theme for the park which is California in the 1920s. You can see the new sign above, and read more about the changes taking place in Disney's California Adventure here.
