Originally Arnell said it was on Team NINJA's twitter, but then said he must have been mistaken. Then someone said it was on Tecmo Koei Europe's twitter, but there is no such post (and I went back to February 20th) on their twitter. The first time I saw it mentioned was by a fan in our forum who didn't link to the original source, then all following news would link to that fan's post.
However, Kasumi was teased by Team NINJA's twitter, that's true.
Locking this thread anyways as it's already being discussed in the twitter thread.
