After the ending of KH, I had thoughts that Riku might be left out of KH2. Although, according the "secret ending" revealing the darker side of the Kingdom Hearts saga, they had shown Riku, wearing a blindfold. Preferably, because of being lost in the darkness.
Also, the "Unknowns" that are to be in KH2 (Rumours) have given people ideas of Riku yet again being a villan.
Another rumour was spread about Riku being the man character in KH2. Well who knows?
What is everyone's opinion?
