Thanks guys for the comments.
Wotto, the machine does have normal sounds when u hit various shots. The sounds however are music related, meaning the bell noise, the train noise, the crowd cheering noise, the guitar/drum noises and there is definately speech in there as well talking to u about shots n multiball plus various missions etc. Thats how I remember it.
I also understand there may be some software choices, but I didnt play around with the menu although I could have. Was too busy putting the first games on the Pro and having fun.
Overall, its just not music with the audio package. The game plays so fast that sometimes u dont even hear the music so to speak because u are so focused on where the ball is flying around at 100 miles an hour, which is great. The game plays much better with the audio up. It gives u all that the programmers designed when u hear all the unique noises.
And to answer the other question, mine arrives in the first seafreight container with everyone elses at start/mid March. I know that AMD have kept 3 machines, and a lucky operator interstate may have recieved one by now, and the Pizza Pinball site at Newcastle recieved one. Thats the 5 that were airfreighted in at considerable expense. But AMD has the Pinball Release Party on and they wanted to rock the crowd by having no less than 3 machines for people to enjoy. I am assuming after the Pinball Launch Party, the 3 Pro models will stay at the AMD factory as demo models for interested people to play.
Also, I believe the PRO and the LE versions are going to play very differently. I believe the Pro model will play faster, with the LE models playing about 25 percent slower due to the underground playfield and the added bits on the top playfield. If u play someones LE model, go and play the Pro model before u make a decision as to how a AC/DC pinball plays. Same if you play the Pro first, it will definately be a whole different game to play compared to the LE game. Personally, if you had 1 x each machine, they would be like having 2 x different games in your house.
