i would love to see Pilotwings and Kid Icarus make their returns.

what about 1080?

Why should you stop making a game after the series have peaked?
Should they just stop making Zelda's, because OoT was the best game ever? Should MP1 have been the ONLY game in the series?
Should we not have seen a Soul Calibur sequal?
Should Street Fighter 2 have been the last one?

And, should they not have made Mario 64, because the series had a peak at Super Mario World?

A new Adventure of Lolo for WiiWare, please Nintendo, please Hal

Donkey Kong's happened - Donkey Kong Jet Race.

 Who said you have to see a game over screen for a game to be hard?

The first time I realized just how brilliant Super Mario Galaxy was in that cake galaxy level with the moving ground and holes in the ground.  You're just crazy if you think that was simple, especially at the point in the game you got it,  and it was pretty hard.

In most games I would have just thrown the controller on the ground and walked away because it would have been too hard, but not Super Mario Galaxy.  They had a very well placed 1UP and made it not too hard to get 1UP's in general so you wanted to keep playing and not get a game over.  If I would have gotten a game over I probably would have never gone back to that level but since I could keep playing I did and I eventually finished that level.

Most 1-Ups in Super Mario Galaxy are well-placed.  In fact, they're too well placed.  1-Ups always preceed hard sections or places where you're about to lose.  If you are going to lose or die in a stage, odds are very good that somewhere between where you respawn and where you get killed there's a 1-Up. 

Consequently every time I saw a 1-Up in a stage my thoughts were along the lines of, "Oh sh*t, something is about to kill me."  ^_^

Yeah I would definitely say SMG is as hard as SM64 the differences being the platforming in SMG was more complex and compared to SM64 much harder what has happened in the years though has been the skill of the gamer (the ones that did 100% SM64) has become better also the reason for a lot of deaths in SM64 is the camera (most of the time) and controls (rarely but needs to be thrown in there) which was all fixed in SMG, then add in all the 1ups of SMG, 1ups don't make a game easier IF YOU DIE THATS A DEATH it just feels less significant with all the 1ups I mean if you got game over where would you start from? basically the same spot that you would with a 1up it just keeps you from going through the process of restarting going back to the world ONLY to die again, that would get annoying, in fact I played SMG where I wouldn't grab any coins or 1ups and got game over many times it finally got on my nerves and I went back to having actual fun and grabbing anything shiny I could find.

Actually, Denis Dyack himself has put forth hints/rumors about both wanting to develop for the Wii and the idea that an Eternal Darkness sequel is possibly already being worked on (if anything, it's in early concept stages).

Personally, I think Mach Rider and Punch-Out could and should both make triumphant Wii returns.  Mach Rider as an adult M-rated sci-fi action game where you ride through a dark futuristic world destroying things on a suped-up motorcycle.  Punch-Out, well, cartoony opponents with much-better Wii boxing than we currently have.  It's easy to figure that one out--and it seems like a no-brainer.

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.
