Its not sure but i believe there will be because they have unsettled things left that wont be shown on this season. For example white dragon emperor talks about how they r going to battle when issei is stronger and there is only one episode left on this season that will contain how they will save rias so there wont be room for dragon emperor battle. Plus show is really popular and succeeded so i have faith there will be more ;)
