Nintendo once showed a GameBoy Advance demo during Space World 2000 based on Yoshi's Story...
However, Nintendo didn't release any plans on making that demo into a GameBoy Advance version of the game...
Personally, I want a new, fresh Yoshi game (probably will be called Yoshi's Island 3) because I had enough with re-releases, I WANNA SEE MORE SUPER MARIO (or even Luigi or Yoshi) GAMES!!!
I am a pure Super Mario lover!!
...and in no point in the future will he ever be abandonded by me!
I will even drawn the best Super Mario comics ever to exist!!
