Alarming why?
I'll happily repeat myself...
With
the original leak (4chan post has expired) literally saying "Haven’t seen any mention of atmospheric landings." I assume some form of Atmos Planets will be arriving in the New Era update, or soon after. "No atmospheric landings" would have ruled them out until a much later update/expansion.
The leaks contained many specifics of Planet Zoo, PlanCo Ghostbusters, named JWE dinosaurs and DLCs, etc, giving me the impression that their FDev contact (mentioned to be a Technical Artist) is directly involved with those games.
The Elite Dangerous leaks are much more vague, as if the leaker doesn't have direct contact with the Elite Dangerous devteam and is instead relying on hearsay. Supporting this thinking is the leaks have given no details on the next two small updates for Elite Dangerous: first one coming July/August bringing more QoL & New Player improvements, the second end of year with new features/content (the small updates are coming every 3-4 months).
