I am a really good platform gamer. I know that Galaxy was a hard platformer (in many areas) regardless of whether or not I got a game over screen.
It is really difficult to make a hard game that doesn't feel broken. Just because you die a bunch of times doesn't make it a good-hard game.
Edit: On topic: I am pretty sure there will be a new Pikmin. I think Star Fox would be a great transition game (casual to core) because the on-rails aspect makes for an easy to pick up but hard to master arcade style that seems to work so good their - examples of this are the on-rails shooters selling pretty well.
I would cite regulation, but I know you will simply ignore it.
