FTDNA has announced a new 59 Marker test for the Y chromosome. The link above will take you to their page about Y DNA testing and the 59 marker test.
They have also revised their Time to Most Recent Common Ancestor (TMRCA) chart to show how this test will help to lower the number of generations one needs to search for the common ancestor: How many markers to test? http://www.familytreedna.com/faq2.html
The theoretical reality of these calculations will be tested when 59 marker results start to come in from know relatives.
