That’s where the manga is up to date. If the story were to continue to follow the fool’s journey, than this crushing revelation that Haise had would not be an entirely bad experience. After all, even if the tower almost always predicts disastrous results, it also precludes the kinds of rays of hopes that shine when everything is lost.
For predicting ability of this though, the current arc represented by the tower, may end with Haise having a major realization of his identity, or at least a collapse of his pre-conceived notions such as his place at the CCG due to things such as his recent memory/hallucination of Arima, or the sudden appearance of owl.
Next would be the star, which hopefully will be a bright spot for our fool, and insight gained from all of his sufferings to date.
