Next ships will surely follow the 052C line. Make it the 052D. The 115/116 appears to me like backjobs, the projects already approved, the RIF-Ms were already acquired, but the JN shipyards simply worked faster and had higher budget priorities and were finished first.
I believe that the PLAN is taking its time on the 052C, waiting to gather enough information and experience from using the 052B, before all these are consolidated into the 052D design, before the design is set into stone. PLAN still has to deal with integrating the second Sovremanny (139) as well as 115 and 116, so it is going to be busy for a while. I also think there is going to be emphasis on the frigates too, in particular the 054A design with the VLS Shtil-1.
