No. Not at all. I have previously mentioned that delays of Dyack's other projects were reason to be skeptical that Shadow of Eternals would not meet its Q3 2014 release though that doesn't tell the whole story.
I'm pointing out that Precursor Games is an entirely new entity, one in which Dyack is apparently only involved in the development side which makes this the first project where he isn't also running a company. If we are to be believe that Kotaku article and blame Dyack's inability to correctly run a business for Silicon Knight's failings, it follows that a company that he isn't in charge of should fair differently unless, of course, Precursor Game's CEO, Paul Caporocci, makes literally all the same mistakes Dyack made at Silicon Knights.
Many of us here like one game Dyack has helmed so I think we can at least begrudgingly agree that he's not a total **** up when he's involved in a project he cares about (as in not X-Men Destiny). Shadow of the Eternals being such a project as well as one he now can devote his attention entirely to, I don't think it's a stretch that the game would have a better chance of not running into the same issues as Silicon Knight's titles.
Even then, and as I also previously mentioned, I think Dyack not having someone like Miyamoto overseeing his progress and telling him something sucks could be a problem. He's relying on the crowd funding people to do that which isn't the same. There's reason to be skeptical of Shadow of the Eternals which I admittedly am, but not necessarily for the same reasons Silicon Knight's games deserved skepticism.
