Anyone who might know, would not be authorised to say. I am not kidding there, they take the NDA serious.
Also, honestly I still don't consider SR6 having more shortfalls than SR5 at the start, and it at least has errata and an updated CRB PDF. In SR5, Riggers were unplayable without a lengthy discussion with your GM on how to interpret some rules. That said, given the venom some people spouted back then, plus the NDA violations that happened... All because a few people were upset about SR6's rule changes, so they were deliberately sabotaging the company in the hopes that Catalyst would lose the rights and somehow magically another company would want to risk rebuilding the franchise.
Sure, I'd love more playtesting than SR6 had, even though it had a significant amount, some of the rule changes weren't as tested as could be. But the intensive testing some products have, Shadowrun simply is too small for. And the whole NDA violations may have very well have soured them on the idea of larger test groups.
Mod Warning
This is all speculation. As far as anyone knows, there are NO plans for a 7E, especially since 6E came out in 2019 and CGL has not made any moves to show they are even thinking about it, what with still releasing 6E rulebooks, sourcebooks, and campaign books. In fact, even the German side is getting ready to release their Sixth World Core Rulebook, Berlin Edition, set in similar format as Seattle Edition.
Any discussion on this topic will be closely monitored.
Just a mild note, I don't think that's the German side releasing Berlin Edition? It's more for the English, perhaps? To translate from the German Discord:
"The content for the Berlin Edition was written by Andreas 'AAS' Schroth, the new German editor-in-chief for Shadowrun at Pegasus. If I remember a statement in an interview or text, some things from the Berlin 2080 book will be taken up again or presented in a condensed form. However, I wouldn't say that Pegasus content is being sold by CGL, but only that the same author has been hired, who writes about the same topic in a different language and form."
