I honestly don't see the point to traditional publishers in today's world. What do they provide to the system? Capital, marketing, and distribution.
Kickstarter has broken their hold on capital (to a degree).
So what is their raison d'etre?
That's a rather silly question. Indeed, distribution is a lot easier to manage nowadays, but getting capital is as hard as ever. Don't forget that all Kickstarter projects have in common the fact that they are low budget niche games, funded by internet-savvy fans of genres ignored by mainstream publishers. It's absurd to think that you could ever have a Kickstarter funded Call of Duty, Fifa, or any game with a budget over 5 million for that matter.
Never mind how all these projects are ran by famous designers, who may be trustworthy nowadays, but certainly weren't at some point in the past - Schafer wouldn't have become a household name if he didn't spend some time on Lucas Arts' payroll in the first place.
