What I've found over the years is that Sony strike a balance between innovation and copying the competition. When it makes sense, they copy the best ideas of Nintendo/MS, for better or worse. Examples of this are: Move, PSASBR, PS Classic, the list goes on. I don't think there is anything wrong with copying, it works both ways. A good idea is a good idea.
Anyway, I think Sony aren't blind to Nintendo's success this generation, and have probably analysed their success closely.
Part of Switch's success early this gen was discussion of which colour Switch you were going to get. Both the Grey and Neon colours had it's fans, and created a healthy amount of discussion amongst fans and the public. Sony released LE and white models of PlayStation this gen. The White PS4 Pro started out as a LE, but later Sony made it a standard colour. Basically, I can definitely see Sony having different colours at launch.
