I was there, it was pretty awesome

. They showed some artworks and screenshots first and then some actual gameplay, I think it was the world premiere.
Yoichi Wada was talking in japanese and the gamescom guy translated everything. They showed some gameplay as a high level dragoneer, the battlesystem looked different but great, some chocobo-riding, group-finding, the new shadow elements, shifting day and night cycles and a new form of limit break, called "group limit break" where they cast meteor when everyone from the group was ready. That was great

.
They also talked about the inclusion of summons and showed some artwork of them, pretty cool. At the end they announced a beta phase for winter 2012, so I hope it doesn't take too long anymore.
I'm so getting this for PS3, can't wait
