Why suddenly remove anything related to reviews and Q&A that can be read now while leaving the “Review Stars”? Why not remove them altogether and at the same time? It feels like there are some readable content being censored and/or preventing some sensitive content being posted. hmm… 
I wonder what would happen if Amazon.com did the same thing to their store. 
Maybe just retain the Review & Q&A content for now and remove them when the new system is ready to be launched in a few days time and not months nor weeks.
