I dunno why people would be getting concerned about this TBH.
It'd be nuts to think that FDev plan to just keep on providing free content for ED indefinitely.
They're a business. They need to do stuff to earn an income.
As far as I can see, there's only 2 possible scenarios which might be at play here:-
1) "Beyond" is an opportunity for FDev to "coast" for a year, tidy up various facets of ED, spend time focusing their attention on dinosaurs and prepare content for 2019.
2) FDev are winding down their commitment to ED permanently.
If its #1 then LEP owners have nothing to worry about.
If it's #2, LEP owners are SOL, as are we all.
The only remaining issue being whether people will consider it worthwhile to spend money on cosmetic items for a game that might be heading for the end of it's life.
On that issue, I'd suggest that we know for certain, that ED will retain some level of support for at least another year so it'd be wise to base any buying decisions on that time-frame, alone.
