Sure it was more simple back then but with the huge amount of ways to get a message across nowadays there should be no issue with "Super" as long as you have a competent marketing/advertising team.
This isnt a Wii U situation where the marketing was awful during those years and "U" doesnt mean anything to begin with.
Most consumers are smart enough to understand that Super Switch would be a new console if they advertised/marketed it as such.
Most consumers vs Useing a number = everyone.
I just think its easier to market, and will show better results, without confuseing any consumers, if they use a normal nameing scheme.
Same with Xbox, the logical next name is Xbox Two (following the "one").
But if a company wants to do away with logic, and pick a stupid name..... hell its their company, their free to do so.
Just dont think it makes sense to do so.
I think you're misunderstanding my original point, I never said that Super was as easy or straight forward as using a number, I said there isnt anything wrong or inherently confusing about Super/Advance.
