Some speculation has surfaced based around the stamp collecting in Super Mario 3D World. It appears that a Rosalina character icon is one of the stamps that can be obtained in the game (# 1 above), and that there may even be a couple of other stamps with her image (#’s 2 & 3), indicating that she is featured in the game even more prominently than previously thought. In addition to the apparent Rosalina stamps, another stamp (# 4) may turn out to be a character icon similar to the four main icons for the playable characters in the game. Could it be possible that Rosalina and maybe even another character might be playable in the game? It would certainly add to the replay value of the game if this is the case.
