I only played the trial for the ESB table, and the voices are not real. Vader sounds close ish, but you really could not tell the Luke and Yoda voices are not real? Say it ain't so...
Honestly the voice work was jarring enough to me on the ESB table to make me not want to buy it.
It also caused flash forwards in my brain regarding future Star Wars (and even the upcoming Star Trek) physical table.
What if Star Trek 2013 goes the Avengers route and does not have the movie voices? It would sound like this... terrible.
It is a shame that the voice work has become so difficult to access. At $10 for non-original voices I would pass, at $15-20 with the actual voice rights I would probably bite.
These physical tables, and even cheap downloads, end up sounding like cheap knock-offs.
Edit: I also wondered about The Hobbit. Will it have real voices? Or will Gandalf be played by the woman who subbed for Glenda the Good Witch in WoZ. The journey is the reward indeed...
