Well I finally made it through the whole thread and feel like posting my thoughts.

I think that the game will most likely be hockey. It matches the hint, as hockey is the only of the three mentioned games which has not already been done. Being a sport would follow the pattern so far (while ultimate Frisbee is a sport, the actual game was very little like it).

I believe it will be played with balls, similar to street/field hockey. This follows the ball/no ball pattern and matches the GDC's expressed desire to move towards more common scoring elements (as opposed to carpet pucks etc).

I think that while assists is a main part of the hint, coopertition points are not necessarily coming back. More likely is an increased emphasis on strategy/cooperation between teams in alliances. As suggested before, getting ranking points for assists would promote teamwork and fit well with a hockey game. At the same time, the new KoP chassis enhances modularity, allowing one robot to adapt to multiple positions or roles.

*Edit: regarding the number three. It could be a red herring, as it has come up multiple times in the past without being significant. As someone already mentioned, hockey is played in three periods. More interestingly, it is played with three inch diameter pucks. Likewise, street hockey balls are usually of three inch diameter,
