This trailer was shown at the Tokyo Game Show last month, and finally a high quality trailer has surfaced (a rough translation is in the video’s description).
It is nice to see some new enemies and gameplay elements that are not in any of the previous Kingdom Hearts games. Some new worlds will make this game feel fresh, rather than Kingdom Hearts: 358/2 Days. Furthermore, we learn that Vanitas can wield a keyblade, most likely making him Ven’s antagonist.
