As well as the new translation of the Contributions to Philosophy, which I’ve mentioned before, Indiana University Press also has listed forthcoming translations of The Event (Gesamtausgabe 71) and the Bremen and Freiburg Lectures (GA79). The first of these is a manuscript Heidegger didn’t publish in his lifetime; the second lectures including the 1949 ‘Insight into that which is’ lectures that were published, in variant form, as ‘The Question Concerning Technology’, ‘The Thing’ and ‘The Turning’. Continuum also have Basic Problems of Phenomenology 1919/20 listed – one of the earliest lecture courses (GA58).
