The quotes show that they have a certain clear version of this game that they want to accomplish. Also they are already 4 months into the development, so everything is planned and analysed, much more than Wasteland 2.
This is not a project that is just made because they can, this is a project to revive in certain way the Looking Glass Studios, therefore i believe that they will make after an successful Underworld release, an System Shock 3 Kickstarter. Looking Glass went out of buisness, because of their publisher, so it is highly probable that they do not want a publisher anymore. It is even more probable that they want to stand on their own, and because of the high reachability of business and digital distribution, they can do this as an indie developer. The use of Unity and Kickstarter is also indicating this. If EA was behind them, they would use their Engine and would not use the Kickstarter, and also they would have much more advertising. But even if EA would help them to get their feet on the ground, then i would not even give a second thought, and i would give a fuck about it, if EA is their publisher or not, because EA has done personally to me no harm. I think that i don't even own a modern game from EA.
Such a long text for just a simple statement: If you want to have Looking Glass Studios back, then give them your money, believe and hope.
