Just a thought. With many people voting for Apple to get rid of the dashboard, that would be throwing away a good item. It’s also useful to many people (the ones voting for it to stay). The dashboard is in no one’s way, so I dont see why it would be voted out of OS X.
So instead of duplicating the widget functionality from Dashboard to Notification Center, maybe ideally the notification button in the upper right of the screen can be a click to display the dashboard. The widgets introduced in the Notification Center would have been more useful in the dashboard (just to keep the nay-sayers unhappy lol).
