How different will Final Fantasy 16 be from the rest of the mainline Final Fantasy games? Should we even be excited for the upcoming jrpg video game?

The Final Fantasy series has been around and active for several decades now, spanning 16 mainline games and several #FinalFantasy offshoots of the franchise. But to me, the Final Fantasy series was at an all-time high with Final Fantasy 7, Final Fantasy 8 and Final Fantasy 9, ending with Final Fantasy 10. What can we expect from #finalfantasyxiv?
