That's hard to say, as it'll depend on Ishibumi and the popularity of the series. At best, we can guess that it will continue on for at least another year or so, considering the introduction of Sataniel and Oz, as well as the fact that we have yet to meet the other two members of the Four Fiends, among other things. What I can say, is the series does have the potential to continue for a long time.
