Hyrule Warriors Legends on 3DS shows why PS4.5 might not be a good idea.

I know the install base is an issue, but they could always do what they did with Xenoblade Chronicles 3D and just make it exclusive to the newer model. You could argue this is what they should've done to Hyrule Warriors Legends anyway.

No if they do that, they need to call it a PS5.

Your going to see a PS4 and a PS4.1,  that ll be more like the 3DS & N3DS situation.
