As you can see, there really isn't anything majorly new. One of the changes you'll note is that the world map is now visible at the 3DS's lower screen, in similar fashion to how Tales of Innocence was for the DS. The main visuals (artwork) for the game have also been redone. This includes the logo which had its colors changed. The new artwork is most likely also by Kosuke Fujishima. Amusingly though, Asch is placed in a somewhat significant place in the group pose... does anybody else smell a Flynn #2 around here? With how Namdai has been lately, who knows what surprises they may give!
Again, Tales of the Abyss 3DS will be released Spring 2011 in Japan.
