Just decided to analyze console pictures for the 1st time and I see the problem. unlike every other game system. Nintendo has the gamepad as the highlighted thing in the official pictures. the console design I'm guessing was an after thought as it does look very similar to the wii, just curvier. I owned a wii myself.
I can see a lot of people who wasn't fanatically interested in it confusing it with a wii.
I was never interested in a PS4 but I know what it looks like......it's all in the marketing.
