I believe the QSuites were not fitted because...they don't fit! Apparently, someone thought it would just be simple to use the Qsuite as fitted in their 777s but, due to various dimension related factors, the Qsuites are too broad and a redesign has had to take place. Apparently, you can't just shave a couple of inches off the side!
I posted on this yesterday as the aircraft were en route to Victorville:
