Thanks to Lex, Bloody Cloud for the info (and vid!) so far
Here's Famitsu's recap on the event for anybody interested -
http://www.famitsu.com/news/201209/02020568.html
According to what I can make out from Google Translate's butchering -
Scenes/words which impressed -
1# - "Tragedy of Aerith" Many players were stunned by this scene, one saw it at 2 o'clock in the morning.
2# "Opening" position of the camera with Aerith, and the camera/3D work of this/Midgar.
2# "Sephiroth taunts Cloud after tragedy of Aerith - "Jenova's" "because Cloud you are a "doll" (puppet ;p)
3# "Cloud and Aerith's date at Gold Saucer" Aerith's words at Gold Saucer about looking for and expressing her wish to meet the "real Cloud"
# Others - A scene with Cait Sith (not sure which, doesn't seem to be any elaboration according to Google T) "Furious" Barret (again not sure what this means, go google", "Care scene" with Cloud after tragedy of Aerith, while holding Aerith, losing his cool and pouring out his emotions, Red XIII and the truth of his father, Marlene's safety (this could relate to the furious Barret thing <_<), Cloud not being a Soldier, memories of the date scene which will become apparant, Aerith in the Gold Saucer, scene with Reno. These are the scenes which for the fans do not fade.
Also -
"I stepped on the scene Reno corneometer in Utai"
Wat
Aerith's VA talks about her role as Aerith, about it being a challenging role I think, about Aerith's "bubbliness" and manner/way of speech already being rooted as part of the character and also about her marriage to Zack's VA (about it being like Aerith and Zack?)
