Possible Android 5.0 Lollipop lock screen revealed prematurely

UPDATE: Here's all that Google later announced about its "L release" of Android.

The Google I/O developer conference is now officially underway. Sundar Pichai, vice president at Google, is on stage in front of thousands of developers, and the opening keynote is going smoothly. Well, almost. The tech team did a boo boo minutes prior to the keynote's launch, and it seem that they've revealed the next Android version by accident. What you see above could be the home screen of Android 5.0 Lollypop. Is this it, however? We're about to find out soon enough.
