It's by no means a "hint" but in the videos of the Q&A session at champs, Bill Miller mentioned that they are possibly scrapping their plan for 2013 due to seeing this year's game live. I think he meant that after seeing this year's game, they for some reason changed their mind about what they had planned. On that note, he repeatedly said they were very pleased with how cooperation worked out and that it was very hard to seed well if you didn't cooperate. So, I would expect co-op to be as value as it was this year again.
I also recall him
very strongly emphasizing using the kinect in the offseason and that while this year the field did not support on-robot kinects, that may not be the case in future. Therefore, I see on-robot capabilities being a bonus next year or in 2014.
Just my thoughts....
