It's just a bananas layout.
Unless Vortex is planning on offering key cap sets, I don't know how you'd replace the default keys on this board. Your only option is to do custom keys from WASD Keyboards.
I have the KBT Race LE (from you) and a KBT Pure and I'm close to pulling the trigger on one of the Pokers you have left in stock. My motivation? Pretty much any ANSI set of keys would work. Which is really the next step isn't it?
First you buy your board and then the next logical step is to look at upgrading your key caps to either a different color, or different material. Unfortunately, there are some real challenges with boards like the Race and I see the Poker 2 being even
more of a challenge. Case in point, there's an IC for [http://geekhack.org/index.php?topic=38563.0]Special Key Caps[/url] for boards like the Race and Choco to fill the gaps.
I'm not saying you wouldn't sell some, but most of the feedback I've heard from those that are passionate about compact keyboards is not all that positive. Just my two cents.
