The music video of their 33rd "cool" single is currently filming.
It's supposed to be challenging dance routine harder than UZA. (Which is pretty up there) Do note that not all members actually learn the dances for these singles, typically the Senbatsu and UG.
Rumored senbatsu from Stage48, Fan Tweets, Google+.
