It absolutely is, and the flexbeams are what I believe have either failed or been giving them issues hence some rumored new builds. Rumor also has it that next month is supposed to finally be higher speed testing, so it would make sense they would want new components.
Having been involved with X2 and seen S97 blade construction, I can say they are quite similar, despite one being detail designed by a supplier and the other being "build to print" by the same folks.
