Do you think miley cyrus will still be succesful after hannah montanna?

Yes.. Miley is amazing and so talented she already has movies lined up after Hannah Montana ends and she's recording her second studio Miley album as well as the HM Season 4 soundtrack, she'll probably continue to tour and like you said there's Wings, The Bodyguard etc. as long as her fans are there for her, she'll always be successful - both in acting and music.
