There are a number of papers released on the Y haplogroup R1b over the last couple of years. It's high frequency areas are focused on Western Europe, but there are early (ancient) branches of it found in Eastern Europe and even in Anatolia. Some of the papers contend that the higher diversity (versus frequency) and the presence of the earlier branches as indicative of Southwest Asian origin.
If you add the two distant paternal lineage relatives together, R1a and R1b, you get a very high degree of coverage of IE languages. I'm not proposing that either of these two lineages originated PIE but they seemed to have picked it up and expanded with it to a great extent.

R1a1a evidence might be interpreted as supporting the out-of-India expansion of IE! However, there is also an interpretation as an outrageous coincidence.
