Super Mario Galaxy 3

Same with Super Mario Sunshine and Super Mario 64, but there was no sequels, right?
 
*looks at list of unreleased, yet planned games* Let's see here.....*mumbles to self* -er Mario World 2: Yo- wait, that came out, what am I saying...*mumbles to self again* AH! Here it is: Super Mario 64 2, and below it, Super Mario 128. *looks for planned Sunshine sequel* Huh. I guess there wasn't one.
 
If it is realeasd I want to see....
Rosalina have the same role she had in SMG1 with Lubba as assistance
More about Rosalina's past
New galaxies
New upgrades
More exploration rather than linear ie. revert map style to SMG1.
Have more than green stars after compleating main game
More 'sequelness'
Make the Grandmaster galaxy even more agrovatingly hard
Keep Yoshi for a few select galaxy as opposed to him being really overused.
 
Here's what I like about each game.

SMG1:
Less Linear levels
Better Hub
Better Bosses
Better Story

SMG2
Easier to jump in and get going.
Difficulty gets harder and harder instead of random difficulties
Better Levels

Again, making Rosalina a major character again, along with adding the Koopalings would make my day.

I would really want the Koopalings as major bosses at the end of the worlds. Each battle being a little bit different.

That was my intention in that each Koopaling gets a Grand Star. When you reach World 8, you'd have to face Bowser Jr. and the Koopalings, who will all be in a giant robot. After that, it's the showdown with Bowser himself.
 
Maybe a few other bosses could be mixed into the galaxies and at the end of each world you verse a Koopling, I also want Rosalina to be a major character with Lubba as an assistant.
