I won't paste links to his Tweets directly, since he apparently didn't like it.
Speaking of which, if that hull is indeed a 054B, then the 054B's length is definitely a considerable stretch from the 054A (147 meters vs 134 meters). In terms of tonnage, he estimated the 054B would displace around 6000 tons by "doing rough calculations with the Constellation class & 054A's measurements as a point of departure". A displacement of 6000 tons is a massive departure from the 054A, and could be "different enough to merit an entirely new class".
Type 057-class FFG, perhaps?

Besides, the massive stretch of length and displacement on the 054B from the 054A and 054 is actually pretty aggressive, when you compare that to the evolution of Chinese destroyers, especially from the 052B all the way to 052D/DL.
(052D/DL be like: What about us??!!
On the other hand, he also posted a satellite imagery update (Pleiades, 15 January 2023) on the 5 052Ds currently under construction in Dalian:

Looks like the above 2 hulls could be ready for launch within the next few months. The bottom 3 hulls (perhaps minus the hull in the middle), meanwhile, could be ready to launch by the end of this year.
