It's time for a new CANON!

Since a long time I was dreaming about the CANON 5D, but now I am not sure anymore if the CANON 7D might be better for me. I need heeeeeelp!!! I was checking all the technical informations and was asking people for their opinion, but maybe I need some professional help from the ipernity members. I am also serching for a good lense to take great pictures in concerts. Who could help me??? New Photoshootings are coming soon and it would be great if I could use the new camera already... Thanks. :o)
