Kh - The Lost Masters

I was watching the kh 2.5 remix trailer until it almost done. It showed a teaser of Kh 3 but this one shows a hint of the story . 
Note: the word's are not in order but you can watch the trailer in YouTube. 
 
Some say it's was Young Xehanort and Young Eraqus talking each other about that. but I still don't know who's talking since its a Japanese voice actor speaking and their faces hidden , but some say it's Yx who's talking For those who played the Japanese version of the game .

Update: added light grey shadings on the two characters
Update 2 : in a website called Kotaku this is scene
Is actually the intro of Kh 3

It's Too bad that Kh and FFXV won't appear in E3 2014 
But aside from the wait I'm excited for Kh 3 to be released soon
