I've seen quite a bit of assumptions floated here without much to back them up. For example - how much of the playing field does clue #2 show? To determine this, we'll base it off the official field drawings from last year (
http://usfirst.org/roboticsprograms/...aspx?id=11624).
Those drawings dictate that the rail is roughly 18 inches high, and the spacing between the vertical supports is roughly 72 inches - with the exception of the sides next to the ramp (the two fully visible sections in the clue) - those are roughly 49 inches wide.
Using that and a simple ruler, we can conclude that we can see roughly 175 inches of the side of the field - or 14.5 feet. The field the past few years has been 27x54 feet, with the 54 foot length the one we can see here - this means we can see roughly 25% of the length of the side wall of the field here - if we assume a similar 4-gate setup as years past, this becomes 50% of each side wall.
Also using a handy ruler, you can deduce that the bottom right corner is roughly 84 inches (7 feet) from the side wall - that's halfway towards the center of the field.
Put all of this together, and you can draw out a little diagram that shows what portions of the field are visible (the shaded regions below). Also included here are the possible locations of a third gate, as people have been speculating on that.
Given this visible area, what can we conclude about the game? Well, there could be no field pieces, like 2009. There could be a huge wall and overpass like 2008. There could be a huge central rack like 2007. There could be goals like 2006. In short, there could be anything, because we can't really see too much, even after we multiply it by 4 (or even 6).
Of course, there's still a lot of speculation in what i've come up with... but it is grounded in quite a bit of fact and in simple economics - it's highly likely that they aren't going to radically redesign the field, since that would require completely new fields. Reusing what they've had in the past as much as possible makes sense.
