In Revision 247 (the latest update at time of writing this thread), Nexon translated new gestures as well as their usable gesture coupons.
The gestures themselves have actually been in the client for awhile now, but before this patch the gestures as well as their coupons were untranslated in Korean.
It also appears that new gesture keywords were added as well (separate from the ones in the video above), since Nexon likes to use keywords as flags for various things. Having specific keywords adds the corresponding gestures to the gesture window. The new keywords they added with this patch, while they do add new entries into the gesture window (untranslated of course), they don't currently seem to play any animations.
Seeing as these got translated in the latest patch, I would not be surprised to see the coupons pop up in a gachapon some time soon.
