There are some already leaked screenshot of 4.4.3 but today we found something interesting, new screenshots have just appeared on XDA that purport to show a new look for the Google Dialer in Android 4.4.3. The contacts are arranged in a series of cards with contact photos instead of a traditional list. It's quite a departure from the current look. Here you can check from the original thread at XDA
The cards show a contact picture when one is available, but otherwise it's a colored block with the first initial (like the Gmail app). The dialer search box is still up at the top and the blue action bar is at the bottom. Since we only have the one dialer screen, we can't confirm that blue top action bar posted by the Nexus Twitter account the other day.
The screens were taken from a Nexus 5 belonging to a friend of the original poster. This person might be a Googler, judging by the names on some of the contacts. However, there's a task killer icon in the status bar, which is pretty weird. It would be odd for Google to tweak the dialer so much in a 0.0.1 bump, but we'll have to wait and see what happens.
