I haven't talked to DPR specifically about the discuss feature. If it was re-implemented i would only want 1 thread per vendor not 1 thread for every vendor + every product + every product list.. Thats just my opinion. In regards to the OP.. Every feature of SR will be implemented with the exception of perhaps the discuss button. After that some new features may be implemented, but lets not get too far ahead of ourselves  DPR Is aiming to get at a minimum every feature implemented as quickly as possible, but these things do take time.
