Perhaps, the 5 is related to the musical group "Five for Fighting", whose 2006 album was titled "Two Lights"?
Could it be that there will be 5 robots, playing against each other?
Could it be that there will be 2 stop lights, 3 colors that control when you can stop or go?
I expect that the diamond plate is refering to diamond plate pattern, but it might not be metal - this pattern is also available in 4x4 rubber mats that interconnect to create a rubber floor. It's used for protection against dropped weights when weight lifting. It comes in red and blue, and can be found at
www.ivanko.com, or then again, it could be aluminum like the ramp was last year.
The disc/round shape is obviously NOT a disc at all, the top is flat where it connects to something. It could be either a flat platform or a ramped platform. I wonder if the 5 is the # of points for getting on this elevated almost round platform. Maybe there are other platforms with others #'s - 4, 3, 2, 1.
The blue color surrounding the platform would give one the impression of being liquid, but it is only the "perception" that it is water - it isn't really water. The game piece probably has something to do with water - something from water, or something for the water.
That's my guesses, excellent clue, as it leaves alot to the imagination.
I'm okay now to wait and see.
