If a video of the Nexus Prime hasn’t got you excited enough, screenshots from the device in question have begun to appear online. They confirm the version of Ice Cream Sandwich to be Android 4.0 and that the Nexus Prime is indeed codenamed ‘Tuna’ like the video owner said. The overall UI is pretty much a smaller version of Honeycomb, which I’m fairly excited about — I may even go back to stock Android from my current TouchWiz ROM on the Galaxy S II. Screenshots below for your viewing pleasure.
