In the video below, you can make out the new lockscreen and shortcuts, auto-rotate animations, holographic UI, Linus 3.0 kernel, new camera app, revamped notification bar, new app drawer with widgets, new camera modes and a new multitasking UI. You can also see that Google apparantly seems to be pimping their own apps pretty extensively with a "Google Apps" icon that opens up a tray containing a number of featured services.
Already the tech community has become divided over whether or not the video is a fake. Some claim there aren't enough sweeping, drastic changes to proclaim that this is the new UI. What do you think?
