I took a look at the Di Cristofaro et al paper (co-authored by Roy King, Underhill, Natalie Myers and the Estorian Bio Center researchers), Afghan Hindu Kush: Where Eurasian Sub-Continent Gene flows Converge.

It contains results for Middle Eastern populations, "Jewish" populations, and some European ones.
I hesitate to say any of this is necessarily authoritative, as they strangely sampled in very few places in Europe, however some interesting things did appear.
The autosomal results can be found in Figure 2 and Figure S2.
As to the light green component, the authors state that it weakly peaks in two places, the Caucasus and the Indus basin, and covers all of western Europe to the western parts of Russia, and even to the extreme west of China and half of India. From the map, it looks to be most dense south of the Caucasus, in the southeast corner of the Black Sea (extending into Armenia?) and on both sides of the Caspian Sea. The graphics are terrible, but as far as Europe is concerned, to me it seems stronger sort of east of the Rhine, and particularly in central Eastern Europe and part of the Balkans. (This affinity between central eastern Europe and the northern Near East also showed up in a recent study of mitochondrial dna.)
The authors further state that the light blue component has it's highest frequency in the Levant (Syria and Lebanon) and "is present westward in Europe until the Atlantic Ocean and decreases eastward toward Afghanistan." To me, this component seems from the map to be centered in the heartland of agriculture from what I can tell, (eastern Turkey, Syria, the Levant generally) and seems to be strongest in Italy and west of the Rhine.
The blue component is said to be most frequent in northwestern Europe, and decreases with latitude as you're going south.
These are not the European components as we have seen them in Dodecad.
In fact, they look to me very much like the Geno 2.0 results, although the "Northwestern" component is more dominant here.
In Geno 2.0 the components are called Northern European, Southern European and Southwest Asian. (And, of course, Underhill is a co-author here.)
The "West Asian" component here, which was called Southwest Asian in Geno 2.0, looks to have affinities to what Dienekes called the Gedrosia component, although it is more frequent than appeared from his analysis.
Is this tracking the elusive "Indo-European" component? After all, one of the stated purposes of the Geno 2.0 project was to find and track them?
To show how far we are from Dodecad components, the Sardinians, unique as ever, have no West Asian, which comports with previous analyses, but here they are 60% Northwestern and only 40% Neolithic farmer? Mediterranean?, Aegean? eastern Mediterranean?
I also took a look at the French and Italian results (labelled North Italian, but samples were taken in Tuscany as well)
The French appear to be 60-70% Northwestern, 10-20% Mediterranean(?), with a median of about 18%, and slightly more than 20% "West Asian".
The Italians seem to be about 55-60% Northwestern, 25% Mediterranean(?) and 20% West Asian.
The West Asian seems to average out to about 20% in all the Europeans.
Any speculations are more than welcome!
