This could possibly be the design of the Next-Generation Corvette or NGC (snap from the Navy's official INS Surat video which included a look at the Warship Design Bureau offices):

Flush fore deck, enclosed RHIB/multi-mission bay, MFSTAR radar mast. Source image is too bright to make out any other details definitively.
Seems to be a 16-cell VLS up front (maybe Barak-8). The radar arrays seems to be horizontally spread like on Israel's Sa'ar-class corvettes unlike the Indian DDG/FFG setup which has a 'full' circle:
On Kolkata-class:

Alternatively, it's possible that this isn't MFSTAR at all - but rather the BEL-developed MFR-X (which also equips the NGMV ships) in a MFSTAR-like mast. In that case, the 2 x 8-cell VLS up front could be VL-SRSAM instead.
I think there could be box-launcher based SSMs (NASM-MR or BrahMos-NG) amidships behind the mast but it's hard to see. Same for the possibility of a second set of 16 x VLS amidships. Though the latter is unlikely.
Either way, the 8-ship NGC class would be powered by gas turbines (possibly MT-30 with IEP) and some previous estimates placed the likely displacement somewhere between 3,500 and 5,000 tons.
