I'm pretty sure that next week isn't the final chapter of the arc. While that's possible given that next chapter is supposed to be 33 pages, I think ANN's just mistaking the next chapter title being "Tartarus Arc Epilogue" and advertising for the arc coming to it's conclusion for the next chapter being the last chapter of the arc. I expect much like the prologue and other parts, these next few chapters will be wrap up before we start the next arc.
