that the fun part about this, speculation by analyzing every bit of info we can take of this teaser.
but one thing bother me a bit....why show us this fight? yes the monk will be the job of the derplander... but it was a given with ala miggho as target. this character seems important, since yoshida did say we will learn more about it in the 3.5.

it can be yda or maybe her sister or another character coming out of nowhere!
who know.... but why show us this part? why not show us the part of the trailer that was pointing to ala miggho.... every bit of information given was not given without be thought over.

is like the picture of Zeno when you see the weapon and the scabbard what you see? for me is katana without one doubt!

they did know that we will think about it, that we will analyze this stuff. then maybe they are hint to some stuff... or maybe not. but actually it's all we can do until december!
