I know I'm going to regret this, especially since I suspect the drama is kind of driven by the OP's sensationalism, but I want to get this off my chest. A few hours, and glasses, past and I would not have posted this, but I will now.
I actually worked on Mask of the Betrayer. I was a tester. Technically, I was quality assurance, but I wasn't really all that good. Some of the other QA guys earned the title. I never thought I did. Hell, I shared an office with the head Obsidian QA guy who also did some of the design work in the game. He did the quest line with the legalistic devil and the quest where you had to submerge yourself in ice cold water. I thought he could be a real pain sometimes, but I respected that he had drive and talent. ...And that was the head QA guy. The design team was top notch. You might know that Sawyer wasn't one of the designers on that project, but he was intimately involved in the process. I will disclaim that I'm a huge Sawyer fan, not just because he was willing to go out on a limb and give me a chance to experience some of the industry first hand, but also because he was so gracious after I clearly let him down. Once I arrived and realized how hungry and talented the devs were, from the lowliest QA Atari employee to Feargus, I knew that I was out of my depth. I'm a hack without the drive and skills to compete. ...But these guys... these guys are the real deal. Take Alvin, for example. Here's someone who is excited by his job and wants to make a something of himself in the industry. He wants a name and so he's spending the time here, listening to what the fans have to say and learning his trade.
I've never met Tim Cain, but I was impressed and sometimes even awed by the people I met at Obsidian. My initial faith was somewhat vindicated by KotOR 2, but New Vegas truly shines. Even with the constraints of the engine and the vision imposed on the team by Bethsoft, they managed to create something I firmly believe is a work of art. I have all sorts of problems with so many of the parts, and yet the whole confirmed what I knew all along. Obsidian has that certain something that puts them in their own category. Even MotB, using the NWN engine I hate, building on the NWN franchise I despise, was a product of real genius. I've gone on too long already, and I *know* I'll rightfully feel foolish when I sober up, but these are the guys. If we want to return to the things we loved, whether it's Monte's tactical combat or Jaesun's epic grandeur or even my personal story about the nature of a man, then this is our best bet. This project, defying as it does the craven publishing houses, is our chance to break out of the mold and start fresh. Let them have barbarians and tactical combat. That was part of the ol' Infinity Engine games also, after all. It doesn't mean the writing will suffer or that the story will be less personal or that any of those things you loved about Torment must be diminished.
