When infinite flight announced they were gonna add the 737 max 8 , there was a thought that came to my mind that this particular aircraft will be the first Boeing aircraft to have a new primary flight display , and once they add this new aircraft they are gonna be shifting their focus on updating the 787 IMO with a working cockpit instrument with modern primary flight display similar to the max.
This is just my opinion of what the devs are gonna be doing after 737 max update so only time will tell
