Quoted from Crile1:The first time my daughter yelled out "Multiball!" When Smaug breathed fire, priceless.
My wife & I did the same thing. We bought TH without seeing the movie because we liked the game play and entertainment value - the music, fx, lights, and video integration gave us chills the first time we played it. My son bought us the movie trilogy so that we could understand the plot of the game a little better. As we watched the movies, we would do the pinball call outs when we saw the movie clips used in TH and would point out the voice call outs when we heard them. Our kids laughed at us because we were doing the backwards association to the movie.
I have no idea ... just one of the rumors/wishes on these threads. Toy Story I "think" is a for sure thing, but will not be #4 according to some people with JJP ties. Guessing that will coincide with the next movie release in a couple of years. I'll likely be in on that one if they do that theme and game play well too - in typical JJP fashion.
