Did Planned Story Content Ever Get Leaked?

As we’re all mourning the pending “Anthem goes to live on a farm upstate”, I got thinking of what could have been. Specifically I remember at launch BioWare said they had several regular story updates planned and I even remember a picture they posted of the cast in mo-cap gear implying that they were actively working on new content. That obviously went into the bin when the launch was not, um, as smooth as expected. Has the planned story content ever been leaked? For all its flaws I actually did like the world building in Anthem and it would be interesting to see where they wanted to take it had everything else not gone to shit.
