I heard this week about a new edition of the Eusebius Commentary on the Psalms. It’s very good news!
This monster work has survived in a rather curious fashion – the section on Psalms 51-100 has been transmitted directly, which is pretty unusual for an ancient biblical commentary. But the sections on the other psalms are recovered from medieval Greek biblical commentaries – catenas – and the status of these is often very suspect. The Patrologia Graeca edition by Montfaucon is not reliable.
The new edition is a project under the august auspices of the Berlin-Brandenburgische Akademie der Wissenschaften. It is being undertaken by a large team of scholars directed by Prof. Christoph Markschies. In theory it is a ten year project and the edition is not to be completed before 2021. My guess is that it will run late!
A short description can be found here, at the top of a page dedicated to a series of projects (including an edition of the homilies of Severian of Gabala, scheduled for 2022-2032!).
