Google Now’s predictive cards were cool, they’re back and available in Assistant now, although they may take some time to get to you as with all things google.
The predictive cards tell you when your sports is sporting, when your planes are flying, and other useful things such as how your stocks are crashing.
They’re available with a new button in Assistant, and generally look like they used to when it was Now. It’ll get to you when it gets to you, but currently it’s showing for me with a long press of the home key and a tap of the card index.[Google Blog]
