If the big 3 could only make new IPs from now on who would have the best exclusives? who would sell more?

Sony>Microsoft>Nintendo

Sony seemed to be much more interested in creating IPs this gen and Sony also has the most first party studios to work on IPs. Microsoft has a load of money and if forced to make new IPs they would probably buy a few studios and invest a lot into them. Nintendo I would assume do the same thing and buy a few studios but there system would hurt tremendously sense Nintendo systems thrive off of the Mario and Zelda games without them I would imagine the system would bomb.
