Yeah it is unfortunate, but not unexpected. Bail even said apparently because it performed very poorly its only hope at staying in serialization was if other new fresh series were doing worse than it. And that did not seem so likely, so yeah. Well, post the last chapter then when it hits
What was keeping it alive for so long was two things. One, Kishimoto was the mangaka, and two, there were about 3-4 series last year that were up for cancellation before it and WSJ had hit it limit of how many they cancelled per year. That gave this manga more time, but really because of how the manga was done it only let him finishes of the series as quickly as possible.
For whatever reason Samurai 8 was trending on twitter, and its confirmed that the manga will end with the next chapter.
Kinda ironic that the big Bleach Announcement led to this.
Its treading because it was announce the next chapter will be the last chapter and the Pro-ending fans are trying to justify why it being cancelled. Mainly, it wasn't bad and if only it could have hit Western shore sooner it would have survived, and Japanese have poor taste.
It wasn’t very engaging from what I could tell. Nothing really stood out in general. To keep an audience engaged you either have to give an intriguing story worth investing the time in or give the Protagonist a sympathetic and defining goal that makes the audience want to root for said protagonist. As far as I could tell Kishi did neither. 
It had a simple goal, find the keys to unlock Pandora's Box to bring about peace to the galaxy. Then he made it complex in order to tie Hachi to the story; he and his brother are the keys and his existence prevents them from becoming such also their another box.
The main thing I will say is that was a problem story-wise was, he was too focus on getting into space. Or. He was too focus on getting the story started to focus on establishing the story's setting. Vaguely here what happened before going into space. An intro chapter. A few chapters hanging out with that kid, Ten chapters of Hachi/Anna while the villain was coming. (In these chapters also Daruma sometime gives lectures to Hachi about basic Samurai know how, and him questioning Hachi's father.) Then space. Even going into space was pretty much just, well the prologue is now over so lets get the story actually started. This manga should not have gone into space before at least chapter 50 and those chapters should have been use to establish the setting and the main cast. By having Hachi explore his home world, learn more about aspect of the society of this setting, interact with as many people as possible to see more of his personality, and learn from Daruma. Instead, all this story has is a bare bone setting and most of the information comes from a talking-cat that never stops lecturing.
Also, it does not help that kishimoto made the primary abilities of this setting multi layered with the locker-ball, cyborg body, soul sword, schools, princess bonds, robot animal mount/armor, and war god among other things.
Most of the cast isn't bad in concept, but without much focus they are all very bland. Daruma is a frustrated mentor that has a tortured background but not much focus. Hachi is too idealized. And Anna is too much like Hinata as the heroine. Those two clown that join them in space are pretty much are teenage Madara(mixed with Suigetsu) and Hashirama(mixed with Sai).
The romance was honestly more interesting to see how much of it was NS inspired, and to see how much the ending & backlash of Naruto's ending affected him. The problem is the characters that made up the couple weren't that interesting so it was hard to invest into unless you were trying. Also the ten chapters he spent on that could have been used to focus on other things especially so early into the story.
Also, the art. Its parts look nice, but it was too cluttered, which made it hard to know what was going on.
