To start off, there's been some mention of a Type 52E destroyer since a number of months ago but the name seems to be spreading around a bit more this month. I think this is a video of a TV program and not some fan-made (but maybe still a touch of fan edits) with mention of the Type 52E. It's probably mostly based off of the Type 52D but uses some technologies from the Type 55 destroyer such as a new radar called model 383.
Here is the text from the video:
From the video is these images of a CG model and a physical model that can be found elsewhere on the net. It seems to be that these are older images and are of an early concept design for the Type 55 destroyer. Of course the Type 55 destroyer still came out fairly different and bigger than the following concept.
The big black rotary radar on top of the tower is probably the radar that is said to be planned for the Type 52E. Note the difference between that radar and the one in the same position on the Type 52D.
