Those are just rumors but even so, throwing Legolas in even maybe for a cameo (maybe one appearance or something) is not too far off since he is King Thranduil's son. Now, about Arwen, I'm not sure but at the time Bilbo and the gang went to Rivendell, Arwen was in Lothlorien so...
Because it's a movie? Everything and everyone which are popular are always attached with rumors. It's nothing new. And Legolas and Arwen are pretty popular, with huge fanbase, and to know that they are children of two of the characters in the "The Hobbit", fans are hoping to see them. I even think there are also rumors about Gimli being there.
