To be fair, EDO isn't out yet and, if FDev follow their usual path, it won't be everything people hope for.
But it'll also be there, and in game, and something FDev are likely to iterate upon and improve.
If ED: Odyssey starts off with what was shown in the teaser implemented I'll be pleased enough then and can wait for them to gradually implement more. So many impatient ED players were sayihng FDev would never do spacelegs, or if they tried, it would be only spaclegs or atmospherics. I was one of the few who anticipated they could be doing both.
Why do I feel FDev has more support for ED now? Well having seen what positions Frontier were hiring up to two years ago, and some of their financial and investor relations brochures, it looks very reasonable that Frontier had expanded successfully especially after releasing two more successful games after Planet Coaster, namely Jurassic World Evolution and Planet Zoo. The job descriptions emphasized "cross development" where devs on one game would eventually be rotated to work on another. I also saw in the financial brochures a diagram showing Frontier's goal to "stagger" development and rotate on their current game IPs. I think very much so, it's back to ED's turn where they've said it's a "new era" for ED, as well as the biggest update to the game being worked on since game launch. And it'll be a paid update, effectively another "season". I also had brief pm contact with a member on the official forums who later got hired by Frontier and became a dev for ED. The last I heard from him almost two years ago, was that the dev initiatives for ED's new era were substantial and motivated, and were going to be so amazing when the public finally finds out all the great new cool stuff they are working on for the game but only when Frontier announces each detail on their own schedule. So absolutely ED's initial "ten year planning" was not stalled or ever abandoned, even if delayed by the PS4 port delay and other unanticipated challenges, and continues on from year five and six now. (that's all I'm going to say about that, all I heard were just that vague summary anyways as much as he dared to let me know)
Of the update issues the impatient of ED complained about, most were free updates that came with later patches of Horizons and the free "season" of Beyond. Sure, new features such as Fleet Carriers had rough edges on release, but that's not unreasonable for a complex addon patch to have rough spots that will eventually be fixed. And yes, when FDev does betas, they are bonafide and legit and release soon enough, with integrity unlike CIG run by CRobs. I think the ED:Odyssey era is going to quite amazing and innovative, where FDev is adding spacelegs to an already massive proc gen galaxy model which also already has a working space flight and ship combat sim working game in its infrastructure already. It'll truly be a first, unprecedented, and another barsetter (at least in its genre. MS' Flight Simulator (12) is looking to be a groundbreaking sim again also.)
