I like asian ninja Psylocke as well, it makes her stand out among all the other generic telepaths and gives her a more hands-on role in combat. Being more dynamic makes her a stronger female archetype than the old "weak mentalist girl" cliche, and it makes her more visually interesting as well. After all, fight scenes and action poses are a lot more fun to draw and look at then yet another "stand and make a headache face" panel.
It's a boost for her character, and I hope they keep both around.
