I will bite.
Yes, the game could flop. Yes, all those people who donated money to the project could see no return from it (other than the entertainment they have already received, if you haven't been there the you don't know). Those are the chances you take with any start up.
No, Brad can't mismanage this project like previous projects. Brad is the CCO, not the CEO. This time around Pantheon has several people to manage the business side of it.
http://visionaryrealms.com/company/team/ Brad realized his own shortcomings the last time and has taken steps to fix those errors this time. That is progress. That is something to congratulate him on.
Yes, Brad's previous mistakes are costing Visionary Realms to have funding issues. It is a mountain they, and he personally, have decided is worth attempting to overcome. And a hell of a mountain it's turned in to.
Anecdotally, the trust fund kid approached Brad, not the other way around. It seems more plausible. But yes, Brad screwed up spending the donated money's they had on hand before the money from the trust fund *kid* came in. Clearly it set the project back quite a ways when the first team left. But they, and mostly he, have picked themselves up, dusted off their clothes, and kept going. And made a hell of a lot of progress since.
I don't think there is anyone left to buy a project like this, and given how the 38studios debacle went down I don't think anyone would if there was. How do you build on a game without any of the team that started it? Sounds like a rough ride for new devs going through the code of the old devs.
For me, the money I donated doesn't mean shit to me. My wife would have been happy to spend it on shoes or a purse or something if I hadn't spent it on something equally as meaningless.
To each their own, I guess. You're either going to enjoy this game if/when it comes out or you're not.
