she never do shoulder tackles if you look carefully, plus feather foot was shown as one of the skill that will be changed/replaced for the monk with stormblood and i will not even be surprise that fist of the wind (that are not that often used) to be take out or changed

the teaser by itself don't say a lot, but with the info given to the keynote we can understand that this red lady is not a monk. what she is can be debated but we will have the answer sooner or later.

anyway, we can only look at the fact that the two character have totally different fighting style and like said before! SE don't have the man power for change the style of moveset based on the sex, nor make the monk (that one of the jobs that are the less needing stuff) get a skill that will make the whole monk move change. you have 13+2-3 jobs to work on, it's way too heavy for only one jobs.

finally we only do get 10 new level at best 5 new skill/trait not enough for explain soo many change.

by itself the teaser don't give anything, even if everything scream kung fu and dance more than the actual monk we have that is more a karate fighter. but with what have said yoshida is possible to take a guess.
