I think these stylistic differences will come through early in competition, but not until then. While last year there were specific hanging bots, or ball bots that didn't hang, or all of the above, teams had to manipulate a few different types of objects.
However, this year's object is a tetra. The goals don't really move, you can't hang on the center goal, so the playing field is leveled as far as object functionality goes. What will set teams apart is their ability to manuever and their strategy. These design processes will change as the competition season moves along, simply becasue teams will start seeing how the game is handled and add unique touches accordingly.
Otherwise, suspense is fun
