She discusses various aspects of DNA preservation (poorer than Central Europe/Siberia due to higher temperature, and potentially because non-freshly excavated samples were tested) which appears to be variable across sites.
A screenshot of haplogroups detected so far (X, K, J, H, T). Interestingly, the X haplogroup only comes from Franchthi cave, although Dr. Papageorgopoulou cautions against very simple interpretations of this fact.
Fst values between Greek Mesolithic/Neolithic samples and Central European Mesolithic ones are high (~0.2), but with Linearbandkeramik they are very low (0.03-0.05).
I'm looking forward to the first publication of these important results, and hopefully they will be soon supplemented with results from Bulgaria and Anatolia that are also to be studied as part of the BEAN Project.
