I'm a philosophy grad student. While I agree that many epistemologists still think it is important to talk in terms of believe/not-believe and justified/non-justfied, I find relatively few epistemologists who reject the notion of credence or think that credences shouldn't be probabilities. Of those who think credences shouldn't be probability functions, most would not object to using a weaker system of imprecise probabilities (Reference: James M. Joyce (2005). How Probabilities Reflect Evidence. Philosophical Perspectives 19 (1):153–178). These people are still pretty much on team Bayesianism.

So, in a way, the Bayesian domination is pretty strong. In another way, it isn't: few debates in traditional epistemology have been translated in Bayesian terms and solved (though this would probably solve very many of them). And many epistemologists doubt that Bayesianism will be genuinely helpful with respect to their concerns.
