While I am disappointed ship interiors won't be at launch, I'm still glad they are considering adding it post-launch. It's a much more optimistic outlook than a straight up "we aren't going to do it."
Myself and another discussed this today. I think the release of Odyssey will be successful in the event this is missing from the start if they don't charge a lot for the DLC type content. If they charge too much, even 20 quid (I'm not UK, it's the price my colleague said) will be too much in my opinion. I think if it's missing the interior-ships and buildings aspect-this release shouldn't be more that 15 USD (whatever that is in quid).
I am looking forward to Odyssey, I really am. I think much like FCs will open up new ways to play. But I can't justify paying more than 15 USD for an expansion that is lacking interiors of ships and buildings.
Edit: The current model for games similar (FPS) are now free and draw their money from aesthetic upgrades (skins for characters/weapons/emotes). While this isn't a Fortnite game- it certainly doesn't have the demographics or market share, that is more of a reason to not overcharge for content that has been worked on for nearly two years (by presumptive release date) and only allowing you to walk around on
tenuous atmosphere planets with minor missions/pvp/pve stuff.
