I am firmly in the camp that wants to see the whole "NEW" Mario Games dead and gone...which they appear to be.
You are probably right that 2D Mario can be a definite system seller, but I would much rather see Nintendo give us a new 2D platforming character and game. Starfy was the last original feeling 2D IP I can recollect and that was just one DS game.
I would however die of joy if Nintendo comes out and says they are Re-making Super Mario World with hand drawn animation.
