I guess that settles it.
No Midship VLS.
I'm not surprised by this since like I wrote before, they built this ship just to stretch it out for the Z-20 and then put on a better radar suite on it (possibly for newer HQ-16 missiles); essentially borrowing from the current tech. They wanted a faster ship; to keep up with others. The ship got bigger because of these requirements.
The integrated masts and that double-sided radar is throwing many off, leaving expectation that this ship should be a next gen FFG apart from the 054A when in reality that's not what PLAN was going for. They are pretty satisfied with 054A and wanted something marginally better.
I think PLAN feels it needs numbers more than a new radical design to maintain their quantity lead over JP, SK, US, and others. Marginal redesign of the 054A into 054B was faster than a complete radically new FFG which might take time.
I say this but then they have just unveil a new Covette, Type 057 possibly, so who really knows why they didn't just redesign and introduce a newer class of FFG. I don't know anything.
