Think I'm in the same boat, and I'm preparing for no physical ticket. It says on the page where I bought tickets that reserved locations are credit-card entry. My confirmation e-mail says e-tickets under delivery, and gives me the option to either go mobile (sign into ticket account, tap orders and show tickets on phone) or to print tickets at home. Of course, the event info page where I bought the tickets says "delivery on all tickets will be delayed until on or around the public onsale date", so this all might become clearer around Monday. Hope that helps somewhat. I've never done a paperless concert, but I didn't have the option of a ticket pickup/delivery, so paperless it is apparently.
