Super & Advance individually are fine, I dont think many people were confused during the NES to Super NES or Gameboy to GB Advance transitions.
Back then things where more simple, a new product = new gen.
Now theres mid gen refresh, add-on items bareing the console name (or consumers assumeing such, with say WiiU).
"new" = slightly bigger screen ect.
The messageing now, is very differnt from what it was back then.
Nintendo themselves havnt kept to a nameing scheme that ll make things easy for consumers to understand.
Basically its silly at this point, its just alot more impactfull and simple, to just stick with a console name and add a number to it.
