I do remember seeing a long time ago that Dave confirmed it would be in the game, but given current events, anything could happen.
I'd read something along those lines as well. Ah well, just over two weeks left to wait, and we'll see. As the version I'm getting isn't out until the 28th, I will be vanishing from here for a few days. I had tried to avoid here after the embargo was lifted, but the castle calls. *Laughs*
Oh, I read earlier on Cox's twitter (not sure if it's already been announced here or not after the initial 'surprise' falling flat was mentioned), that there won't be any extra surprises included at all with the PC pre-order, as apparently, he couldn't pull off whatever he wanted to do. Sorry guys.
