Reggie has a good point. The Wii U had a horrible elevator pitch. In hindsight, it should have been marketed primarily as a Wii HD and allowed the gamepad to eventually be optional. Not sure it would have made any difference, but at least people would have understood it for what it was. http://www.nintendolife.com/news/2018/06/nintendo_says_switch_success_is_due_to_clear_marketing_as_opposed_to_wii_us_failure
I'd rather just give it a new name. Rebrand it as its own thing. Or just call it Wii2. I think it would've made it more obvious that it was a new console.
