If I had to make an educational guess, I would say that Skarlet and Kenshi will probably be released after Evolution 2011. Below are Skarlet's special moves along with the time they appear in the video. All names are unofficial.
Throw - leaves opponent in the middle of the stage. (shown at 1:50)
Blood Toss - Skarlet throws two knives in the form of blood. The second knife can be canceled by holding down the face button, and Skarlet recovers very quickly. Face button can be released to toss knife again. (regular version shown at 1:24 seconds; the canceled version shown at 1:26 seconds)
Aerial Blood Toss - looks just like the aerial version of Liu Kang's b,f+1. (shown at 1:23 seconds)
Diagonal Aerial Blood Toss - looks like Sindel's d,f+3 in the air. (shown at 1:40 seconds)
Blood Orb - Skarlet tosses a blood orb at an angle. Looks slow. (shown at 1:45 seconds)
Knife Launch - looks like Nightwolf's Hatchet with superior range. Notation is d,f+2. (shown at 1:29 seconds)
Knife Pummel - Skarlet pummels the opponent with the knife. (shown at 1:49)
Blood Slide - Not a special move. Command is forward dash into 4. It looks something like Sub Zero's and Cyber Sub Zero's slide with shorter range. (shown at 1:27 seconds)
Enhanced Aerial Blood Toss - looks something like Nightwolf's Enhanced Arrows. (not shown in video)
X-Ray - starts with a front flip. (shown at 3:15 seconds)
Fatality 1 - first fatality. (shown at 1:46 seconds)
Fatality 2 - second fatality. (shown at 3:25 seconds)
