You're very welcome Kent. I wouldn't hold your breath waiting for another company like Sandisk to join Sony and Lexar in the XQD world any time soon, unless more electronic devices (read that cameras, mostly, and perhaps other memory imbued devices) utilize the cards. Their speed and durability are great, but unless the price drops precipitously, they'll be relegated to high end products only, which doesn't bode we'll for their long term product viability. Right now, as far as I know, the D4 is the only product using them, but with Lexar joining with Sony, I've got to believe more are coming down the pipeline soon. I just don't know if that will be enough to draw in more manufacturers.
