The footage starts at the 7:20 time mark.
As you can see, you can collect coins after defeating enemies which have a W on them so for now I will call them "WayneCoins".
For those who play Gameloft games, you know that most of their games are "Freemium" meaning that they are free to download but also contain in-app purchases for you to be able to enjoy the game at maximum capacity. Gameloft earlier confirmed that every game this year will contain that format so one can only assume that
The Dark Knight Rises and
The Amazing Spider-Man will carry that format as well especially since "WayneCoins" were spotted.
The Amazing Spider-Man releases on June 28th and the date for
The Dark Knight Rises is unknown at this point.
