So the Navy released a vague render as part of some other video, and it seems this may be the latest iteration of the evolving Next-Generation Destroyer (NGD) design. The resemblance to Italy's Fincantieri DDX which existed in the older iteration is now completely gone. This seems to be a ground-up new design:

Keep in mind that it's still an evolving design and this may or may not be tentative. But looking at how things are, it seems it'll have a total of 112 VLS cells, comprising:
48 x Small VLS (point-defence SAMs like VL-SRSAM)
48 x Air Defence VLS (medium/long-range SAMs with area-defence & BMD capability like Kusha family)
16 x Strike VLS (for large ASuW/Land-Attack weapons like BrahMos or future Scramjet Hypersonics)
I guess they are not going to go for a universal VLS (so far at this stage anyway)?
