New WP8 Lockscreen Notifications

Has anyone noticed that in Microsoft's new Windows Phone 8 video, the lock screen shows some new notification icons. The video is on this page. You can see it when the video is ending: http://www.theverge.com/2012/6/20/3096667/windows-phone-8-screenshots-features-nfc-start-screen-dual-core

Microsoft did say that they weren't unveiling all the new features today. Could a new notification system be in the works?
