Composer List vs. Stage Leak

EDIT: After looking at the list of composers for Brawl, and then comparing that to the returned Melee stages, I found that my theory does not hold up. I found that Melee’s original composers were not credited if they did not create any new songs. Please disregard the following theory. Thanks to everyone who commented on the validity of this theory.

Here’s the potential stage leak:

Let’s check the composers of the returning stages, with the newly released 3DS composer list to see if the retro stages are more or less confirmed. Sakurai has stated that the 3DS version will have two tracks each. I do realize that it is possible that Sakurai has not released all of the information in order to avoid spoilers. The second box says if the composer was credited on Brawl’s pre-release of composers.

Yoshi’s Story [From Brawl]:

Ending (Yoshi Story), composed by: Masafumi Takada [Check] [Yes]
Yoshi’s Island, composed by: Noriyuki Iwadare [Check] [Yes]

It’s highly likely that this stage will return.
