I don't know if I would go so far as to say that Aladdin is 5B. Look at Camelot. there were subtle (and not so subtle) hints going all the way back to season 2, and we are just now getting Camelot in Season 5.

That being said, There have been some subtle hints and foreshadowing that could indicate that Aladdin is on the radar (although it was at least partially covered in Wonderland).
