there's usually some kind of prior announcement when a series ends in the next few issues. as there is none i'd assume that there are some more chapters to come. they could probably even prolong it like with dragon ball
Its hard to say. While I do find it hard to continue, I think it might be ending soon. But I wouldn't bet on the next chapter being the last. Still a few loose ends to tie up that might take 2 or 3 chapters to finish.
