I haven't read the whole article yet, but it seems that there are few "big" surprises. It basically confirms what we already knew about the relationships between mainland Asians (including South, Northeast and Southeast ones), Oceanians, Americans and West Eurasians. Split times between populations are too recent IMHO (only 34K between West and East Eurasian, incl. Oceanians) and Africans (Yoruba)/non-Africans (~60K on average).
They have found low levels of Denisovan DNA in most of the studied Asian populations (interestingly, some IE-speakers from India have substantially lower levels than other Indians) that are higher in some SE Asian and Oceanian populations (this has already been described in a couple of recent studies).
It's a pity we have so few Australian genomes... I'd love to read a genome project on Oceanians. It seems that the genomic history of that region is very complex.
