The GDC obviously did a Google images search for "moonfish" and took the first image that showed up. This must have been on purpose. The question is why?
A quick Google search for "moon fish" turns up this:
http://www.moonfishocean.com/ right away. Apparently "moon, fish, ocean" is the new zen version of "rock, paper, scissors".
From the website:
"Zen Masters use the game as a test of a disciple’s reflexes and non-attachment to outcomes. The Master holds a pebble in his palm. The pebble remains hidden when the Master plays “Moon” or “Fish.” It is revealed only when the Master plays “Ocean.”
If the disciple can snatch the pebble quickly enough, he automatically wins the round."
Sounds like we will be somehow playing "rock, paper, scissors" with robots and trying to steal something from the opposing alliance. Still 3v3. One "master" robot holds/guards a special game piece while the other 2 "disciple robots" try to steal the game piece from the opposing alliance for major bonus points. Maybe like 2006 with offensive and defensive periods of 2v3 or something.
