Everything the band has said in interviews and in between songs at their show points to them staying around for a while. Ryan and Sean were saying things like, "We need you guys more than ever to back this band again like you did the first time around." Or "We know how hard it is to make it to where we were when we left, but we are excited to work even harder to make it back and do what we love." Those may not have been the exact quotes, but things along those lines were tossed around when I saw them last week. I think it's safe to remove the reunion label from them as they are definitely back. Plus, the way they recorded the acoustic album on off nights of the ATL tour would point to them being full go. If they had no intention of pressing on as full-time unit, they could have just taken their time on that and recorded after touring bc they would have no pressure to release anything further.
