I hear that the results using modern AMS testing will show some of the scrolls are older than originally first thought.
Again, I'm not aware if the results have been published yet, but in this video (thanks for the link Neil

4Q201- estimated between 162 BCE and 2 BCE.
4Q504- estimated between 352 BCE- 287 BCE with a 45% probability. I point that out because the original editor of the document M. Baillet was ridiculed when he suggested an exaggeratedly early date, the mid-second century BCE... The Complete Dead Sea Scrolls in English, pg 364.
If the new dates are correct that means the Tanakh is older than what some modern scholars estimated. There is even some juicy stuff in 4Q504 for my mythicist friends. 4Q504 not only talks about: 'For Thou hast named Israel 'My son, my first-born'..and that Jerusalem is the resting place for the Lord that he himself had chosen...but also for the Trinity, 'For Thou hast shed Thy Holy Spirit upon us'.
