Who really knows. I suspect a lot of revisions are market rather than scholarship driven. Too many I say. I have Ref Study ESV of which was the former New Geneva Study Bible...NKJV I think. My Zondervan NASB Study Bible is my work horse now but I look forward to adding Beeke's KJV Study bible next Fall.
I believe one of the biggest "improvements" was the addition of some color maps in the back of the 2nd edition. Though I don't own a 2nd edition. I have the first edition too. Perhaps, the ESV text may have been updated as well.
