Well she didn't anything too crazy and awesome on my eyes. She still used her SCH book after all. It's not first time we see an aether blade. It's not a new concept in game. This might not be a teaser for a next class at all. Well the first Fan Festival is in 2 weeks. So we will learn at least for 1 new class there. If he does it like on the previous Festivals then we is going to reveal 1 new class at each Festival. The name of the new expansion and a teaser trailer on the first.
