The ASHG 2012 abstracts are online, and Dienekes' summarizes the following:
On the Sardinian ancestry of the Tyrolean Iceman confirms that modern Sardinians are most similar to both the Tyrolean Iceman and the Swedish Neolithic TRB individual (presumably Gok4). You can find my analysis of both in the archives of the blog. But, look here:

This is really surprising if finally true, because it would mean that the West Asian related components we've seen in many admixture experiments are even more recent in Europe than expected. Moreover, maybe R1b has very little or nothing to do with it, which seemed very likely at first. Y-DNA J was probably the one mostly linked to the so called component according to this.
We'll see if something new comes out confirming the info.

Strikingly, an analysis including novel ancient DNA data from an early Iron Age individual from Bulgaria also shows the strongest affinity of this individual with modern-day Sardinians. Our results show that the Tyrolean Iceman was not a recent migrant from Sardinia, but rather that among contemporary Europeans, Sardinians represent the population most closely related to populations present in the Southern Alpine region around 5000 years ago. The genetic affinity of ancient DNA samples from distant parts of Europe with Sardinians also suggests that this genetic signature was much more widespread across Europe during the Bronze Age.
As you may have guessed, I can't wait to get my hands on that Iron Age Thracian. His similarity with Sardinians is striking, because by the Iron Age, I would have thought that something akin to the modern genetic landscape would have begun to crystallize in Europe.http://dienekes.blogspot.com.es/2012/09/ashg-2012-abstracts-are-online.html
