Windows Phone 8 Notification System Concept

We have seen many concept for improving notification system in Windows Phone OS. The above one reached our inbox recently and it was interesting. The above concept still holds the simplicity of the OS even after adding the detailed notification system. What do you think of this system? It seems like Microsoft design team still believes that the concept of live tiles will solve the notification system problem. Are you ok with their idea ?

Thanks to Sujau for the heads up.
