Plus, looking at this from a perspective for possible use in the FRC, it looks like it could end up being a very useful breakout board for more sensors and possible processing a second camera that a team might need if they want to get fancy. What are everyone's thoughts on this?

You could certainly hook them up in a master slvae configutation, it would be a simple as coming up with a communication proticol (through your choice of ethernet, usb, RS-232, etc).
As far as FRC applications I am still of the opinion that 99% of teams dont need any more processing ability than what the cRIO offers. Teams looking to make a modular posistioning system like what wildstang had at one point could certainly use this (it would be over kill but the price point is right). This board is definitely capable of running a second camera and doing onboard image processing, if a team saw a need to do this then this board is certainly a legitimate choice, however I don't think that the current setup and difficulty of autonomous mode would warrant making such a complicated system.
I honestly don't see this as a big deal for FRC applications, a lot of the things that teams would want a second processor to do can already be done with other boards at this price point. This board is very powerful and very cool, however I don't think that there are many applications that require a board this powerful that offer a great benefit to FRC teams and could be completed during the build season. However I have been wrong before and would be happy to admit I was wrong if it means that a team came up with a cool application for this board.
From a hobby perspective I am excited. I already have one ordered through Adafruit, while I have no plans to do anything with this that would require the hardware it has I plan to use it to replace my Arduinos for quick prototypes and testing.

However I saw the schematics posted earlier and indeed it does have pins available for I/O.

Information was surprisingly hard to find, I don't understand why they wouldn't have it posted on their home page but some digging turned up the info I found, and apparently a little more turned up the schematics I couldn't find.
Per the schematics there appear to be 8 Analog inputs and 60 digital I/O (though many of these are taken up by the UARTS and other peripherals, it looks like about 30 are available through the expansion headers).
