The whole "following the repeat" trend of it being time for triple play (2007&2011 , 2006&2012" is kind of a stretch...I don't think the GDC follows patterns that closely. As engineers we're always trying to find ways to understand the system in which the game is chosen but it's really whatever meets the GDC's goals and is a combination between crazy and fun
Speculate on though...I love reading it!
