Not to jinx next year, but...

[Chris is me]

If I had to guess the game next year: It'll involve mass game piece control (many smaller balls), elevated scoring of some sort, scoring in high volumes (large "dumps" rather than a few precise shots). Scoring from range will be an option but not really required or necessarily even a good idea. It'll certainly be a game with opponent interaction to some extent.

I personally really think that rules restricting the number of game pieces the robot can carry are generally not a great idea and that problems with starvation strategies, etc. should be dealt with in the game design, not patched with a rule later on. There are some exceptions (2013 really needed the four disk rule) but I generally think letting the teams figure out their limits works better.
