Well, I was watching the new trailer for BBS and I noticed that Ansem the Wise talks about "that boy" who saves the world each time when the darkness shows up. He also mentions that he can connect with other peoples hearts. Ven says "Our connected hearts are my power!" which means that "that boy" is Ven, at the end of the trailer, Ansem the Wise says "And his name is..." and it shows a picture of Sora.
So I think Sora's heart is connected to Ven's heart, so when Sora became a heartless and Roxas was born, he had the apperance of Ven due to the fact that Sora and Ven have connected hearts.
Think about it, it all makes sense.
