Kinda. Two separate control schemes may not work when operating with a single style of locomotion animations/physics. At best it could feel a little odd and rushed, and at worst neither set of controls may work properly because the design goals were all over the place because of the restrictions of catering to new players and purists separately.
It's possible to have our cake and eat it too, though. Analogue controls don't prevent Ryo from having the heavy, deliberate feeling standard speed movement we had with the tank controls of the OG games. I could even see fixed camera still being a thing, though having interiors that don't require loading to go inside may influence the decisions on that if they run into issues of getting inside with a fixed cam without a transition load to reset the camera each time. Worst comes to worst, R3 = camera resets behind back.
We just have to wait and see what YSnet did with it, though.
