I've just seen that back in December Oxford University Press published Maieusis: Essays in Ancient Philosophy in Honour of Myles Burnyeat. This information is based upon the UK website; the US website indicates that it will be published January 28.
As most of you probably know, Burnyeat is one of the leading specialists in ancient Pyrrhonism, even though, to the best of my knowledge, he hasn't been working on skeptical philosophy lately.
One of the essays is Jonathan Barnes' "Sextan scepticism". I'm eager to read it, but I'll have to wait to get my hands on a copy. There's another essay, by Jim Hankinson, entitled "Self-refutation and the sorites". I assume that, in this paper, Jim in part deals with skepticism.
