Back in the day, the fifth installment was received relatively well and sold decently. The sixth game severely damaged Ubisoft's reputation, but it still sold relatively well (riding on the brand and the series' fans). The seventh game was already met with skepticism, and this skepticism was fully justified. And then they abandoned the project without support, leaving it in an unfinished state with a ton of bugs...
Ubisoft is now in a difficult situation: continuing the series themselves after so many failures would simply be foolish, but leaving it to gather dust as a dead weight is not rational, as they invested a huge amount of money in the project.
Most likely, we will see a new global reboot of the series, similar to what the fifth installment was. Under the wing of a new company, and in a new world. And in my opinion, this is actually good news, as Ashan has become stale and is not developing, and it's getting repetitive - it needs fresh blood. Currently, there are discussions about what the continuation of the series should be like.
