Yes and i see that the researchers from United states are more interested in them then the one in Europe,for example the figurines and cultures from Danube valley were exhibited in New York,part of article;
A Lost European Culture, Pulled From Obscurity
By JOHN NOBLE WILFORDNOV. 30, 2009
Before the glory that was Greece and Rome, even before the first cities of Mesopotamia or temples along the Nile, there lived in the Lower Danube Valley and the Balkan foothills people who were ahead of their time in art, technology and long-distance trade.
For 1,500 years, starting earlier than 5000 B.C., they farmed and built sizable towns, a few with as many as 2,000 dwellings. They mastered large-scale copper smelting, the new technology of the age. Their graves held an impressive array of exquisite headdresses and necklaces and, in one cemetery, the earliest major assemblage of gold artifacts to be found anywhere in the world.
At the exhibition preview, Roger S. Bagnall, director of the institute, confessed that until now “a great many archaeologists had not heard of these Old Europe cultures.” Admiring the colorful ceramics, Dr. Bagnall, a specialist in Egyptian archaeology, remarked that at the time “Egyptians were certainly not making pottery like this.”

Then one of my favorite medievalists South-East Europe Florin Curta is likewise writing from United States,i have read in his articles that he is complaining that in Europe is hard to work whether archeology,history is subjected by some old ideas that are wrong,but are changing not talking about here IE'ans but medieval.
Balkan for some reason is avoided from many different studies despite the importance of this region in the Medieval times,downfall of Roman empire,emerging of new states etc and likewise as we see in much more ancient world.
