Should homeschoolers be concerned about the new SAT?

A lot has been said about the new SAT  scheduled to debut March 2016. Some have recommended students take the well-established ACT to avoid being an educational guinea pig. I have read much on the new SAT and listened to interviews. I am still a bit divided on my thoughts on the new exam.

The SAT reformers tell us the new exam will reflect the high school curriculum more and generalized vocabulary. What does this mean for homeschoolers, who have consistently and significantly scored higher on the SAT than their public and private school peers?
 
Frankly, there is no reason to believe that homeschoolers will not continue to ace the exam.  I mention this because some parents have asked me if they should alter their curriculum given the change in the test. Mastering the vocabulary is one of the ways to score higher on the SAT and since the vocabulary is going to be make more amiable to the typical high school student.

As homeschooler remain committed  to their strong and traditional college prep metho then they will continue to do well.
