Well, FIRST does have a strange tendency to go back to balls after a year of something else, especially since 2002 (balls, bins, balls, tetras).
Much as
some people might joke of inflatable clowns, I'm predicting that there will be some sort of COTS gamepiece. Now, whether that is playground balls or footballs or soda bottles or shopping carts from the local
Piggly Wiggly, we don't know.
(And to think, in four months we'll be swamped by whatever it is.)
