[HTC One X] knoxploration:
FYI, two sample videos--presumably out-of-camera--are now available from mobile-review.com's Russian-language version.

NOTE: THESE ARE STATED TO BE SHOT WITH PRE-PRODUCTION FIRMWARE. Both seem to show significant frame dropping, for me, although I've yet to open them in Premiere Pro and try stepping through frames...
