It's getting a lot of play on the GEN-DNA list but not here so far.
I did a little poking around and it seems S28 is R1b1c10 on Ysearch. A
distribution map shows it spread throughout Europe, from Italy to England, very
heavy in southern Germany, very light or nonexistent in Ireland (basically
the same thing as the list of R1b1c10 on Ysearch). Lots of matches in Germany.

Dr. Faux believes S28 is tied in with the Le Tene and Hallstadt Celtic
cultures.
Dr. Faux also states "this is big, really big."
For R1b1c7, my question would be: "Could this discovery help us identify
where M222+ first originated? And perhaps when? If R1b1c7 split from
R1b1c10 I can't see it happening in Ireland (where are the haplotypes?). We seem
to think R1b1c7 was relatively recently in genetic terms. Secondarily, is
there any need for M222+ individuals to get tested for this new SNP? What about
people who haven't tested for M222 yet? Would they need to get tested for
both?
This reminds me of the excitement caused when David Wilson first tested
positive for M222+.
Here's a link to a site with lots of S28 info.
