I heard a week or 2 ago that Pure Pro may start shipping in late May. However, given how overly optimistic Vortex's schedule, I'd take that with a bag of salt.
On an semi related note. I have been using my Tex board as the "second board" on the desk since I got it. I haven't used my Pures much at all. I really do like the arrow clusters. I guess I am ok with the small right modifiers. I use control and alt + arrows a bunch, and they're pretty convenient to use on this board.
1 thing still bugs me. The FN + QWERT is way too easy to hit to enable the soft switches. I wish they make it that you have to press both FN keys to enable the soft switch modes. If I can get a firmware update that makes fn + arrows = home/end and page up/down. I'd replace my tenkeyless with this as my main general usage keyboard.
