Not sure why everyone is jumping to the TO:1886 sequel being canceled based on this news. That's quite a leap.
RaD was never part of Sony WWS and could have self published (or chose different publishers) for anything/whatever they wanted. They're in a position now to do that. That's literally all I'm getting out of this article.
The parallel here is Insomniac.
Why would they continue The Order? It didn't review well. It didn't sell well.
