The thing I'm looking forward to most are items related to rewards for attempting as well as completing modes and how they relate to qualifying wizard modes. Theres so many cool possibilities.
1. Collecting golden tickets
2. Collecting everlasting gobstoppers
3. Collecting Wonka letters
4. Collecting Wonka bars
Also hoping for a set of 4 Oompa Lompa modes that represent the 4 Oompa Lompa scenes from the movie. Chocolate river multiball or wizard mode is another with crazy cool lighting and sound effects.
