Emails from AndyMark are considered an official communication from FIRST? Could you point me toward that ruling?

I would infer rather that they are legal because they are in FIRST Choice, not because of the AndyMark email.

Re: FIRST Choice

FIRST really needs to come out with an official statement on which motor controllers will be legal and soon!

Re: FIRST Choice

What are jaw couplings used for? (I've linked one of the many on the list.) I'm normally more electrical/programming than mechanical, and this is a new part for me.

Two jaw couplings go together with a rubber piece in the middle to create on shaft coupler with some advantages over just a solid connection. Here is some information from the manufacturer of the ones we have used in the past.

They're used to connect 2 coaxial shafts together (one driven, the other the driver). They generally isolate shock between the components and can handle some amount of mis-alignment between the axes.

Re: FIRST Choice

Considering this post on FRC blog (the last bullet point), I'd consider the Talon a legal controller for the 2013 season

We have 2-3 gtx 480's from them.

And which regionals might that be? :D

We got one at both Portland and Seattle a few years ago. As far as I know, they only did it that year.

The bearings with the groove around the outside, which come in eccentric and concentric varieties, are for the linear rail also avalible in FIRST Choice. It's leads me to think elevator game, rather than winch game.

Then again, we saw the same linear slides in the 2012 FIRST Choice, so take these indicators with a grain of salt. Besides some interesting indicators (IR remote anyone?), I would be very reluctant to deduce anything from this list other than that the Talon will be legal next year.
