I wouldn't either. Where there is smoke, there is fire. The fact of the matter is that even if the stuff about Obsidian isn't entirely accurate, there is probably enough going wrong there that it will significantly impact their games. Based on what has been showed of Avowed so far, I think we can clearly see some red flags already.But I don't predict good things for that studio in the future.
As for Avowed's performance, its hard to say. The studio is more well known than some of the studios that have had major flops on their hands this year but they aren't BioWare or Bethesda either. Starfield has a lot of the problems that Avowed has (given that Obsidian basically just copies Bethesda's homework) and it did relatively well. So we'll see. But then again, Dragon Age had brand recognition and the studio is was well liked by many and it still utterly failed.
