Here's what I'm thinking...
1) The whole banana thing was just to make the line for having a "bunch" of clues. Which brings me to my next point...
2) That post saying a "Bunch" of clues means that the picture gives away more than one element to the game...
3)I have two different thoughts on the words "slip" and "peel" in that post...
They are there to enhance the bannana theme

. Or they are there to show that their will be a slipery aspect to the game. However the picture shows the game on the traditional carpet, meaning that the slippery aspect must be introduced in the scoring portion. Still working aout how this could be...
4) Enough with the follow up post... Back to the picture... The whole water-esque look of the picture could be a few things... To fuel threads like this about a water based game (however I don't think this is correct, because a post was quickly made downplaying the possibility of a water game), meaning that the water feel of the picture represents something else. I would just like to go on the record that I don't think any water at all will be on the field, it sort of contradicts the whole 'saftery first' thing. So... again... I have no idea what the water may represent but I'm working on it.
5) There is one robot on the field and three fish. Now I have a few ideas on what this means. First, it could be that points are allotted on a 1 v 3 basis, with there being four rounds, each robot getting a turn to be the offensive robot, and that being the period where that robot can gain points for ranking. However, there are a few factors working against this, it would completely do away with alliance selections, and in the picture a blue startign box can be seen. This blue box probably means there will still be alliances. Now my other thought (which I think is the most plausible thing I've said in this whole post...) on what the fish could mean is that they represent three ways to score. This wouold tie in with the whole "slippery" way of scoring supported by the bananas thing earlier. The other reason I think this is true... take a look at the uppermost fish, it's one of those fish who have a light hanging from their head. I'm thinking it represents the light for the camera. The other two fish look smaller, but not as tough, and they do not have a light. Meaning that those will be the other ways to score and will not use a camera and are not as tough to get but will produce less points. The textures and colors on the fish could very well have something else to do with how to score, but I'm saving that thought for another day...
6)The lights reflected on the back of the robot... On this one I'm gonna say take it at face value, those are the colors for the Autonomous light. However I did have another thought, why are the lights reflected on top of the robot? Could this mean that there will be colored lights high above the field that the robot can use to find position during Auto, it certainly would make for a more complex Auto, something that seems to be a pattern as the years go on...
7) I know that the design on the thing hasn't changed much through all the animations, but why does the robot still have a plow on it? Could this also be a clue on how to score? Once again... I don't know how... Still working that out...
Anyway... I know I left alot of blanks in this post... but it's everything I've though of when I looked at the picture. Just a side note, I love how the picture came out so early this year. It gives me something to ponder when I don't want to listen to whatever the teacher is saying in school...
