I can confirm that there wasn't a window switch, or window crank located on the access doors on the SEMA FJ. I think they are fixed.
The all black FJ shown in the video is cool, but it takes on a very different personality than the other FJ's.
In my professonal opinion, the white capped roof is a really important visual bridge that connects the FJ Cruiser back to the original FJ40. Without the white roof, the FJ has a slightly harder time to differentiate itself from all of the other "cookie-cutter" SUV's out there.
My 2.5 cents,
