It's very ambitious, I have my hopes up, but I'll remain realistic.
That list of features is just what they think should make it in, and right now it sounds great. But many development teams often eventually have to cut corners, or modify originally-planned or partially completed features, maps, characters, story lines or whatever you can think of. Now of course the bigger the budget the more stuff you can work on, and the longer you can work on it, and their engine might allow pretty much everything they're planning to do. We'll see, but to be honest I'll just start to be really excited about it the day they release a list of features that did make it, then and only then, for me, will be a matter of time and a total " Shut up and take my money! " pre-order.
