✍️ What we know so far

Automatic note by LuaCat Games, built from what we know about the coverage (who reported it, how many sites, the story’s history) — not a translation or copy of the source.

This comes from Polygon, which does its own reporting — for now, it's the only coverage.

Bottom line: Safe to take the main point — it's the fine detail that sometimes shifts later.
