Bellosh101: As long as the scripted dialogue during missions is of relatively the same quantity to be found in TF or less, I don't think chattiness should be a concern. However, I do think there should be options to silence either the generic pilot chatter or all the dialogue, just in case somebody wants their XWVM experience to be a little more purist.
Silencing all dialogue would be as simple as lowering the Voice volume level to 0, but that would also remove the original generic chatter ("Roger", "I got' em", "Target destroyed", "Docking operation complete", etc).
About disabling only the new dialogue, we can always add a new preference option somewhere.
In other order of things, expect the first test release download later today or tomorrow. Please, have handy the email address you used to sign into the tester application, since you will need it to run the game.
