I like how you assume that the notoriously restrictive Sony would allow Frontier to release Elite Dangerous & Odyssey on PS5 without also releasing Odyssey on the ancient PS4. It's very funny
Unlucky that Sony won't allow GeForce Now on Playstation, that restricts so many possibilities unlike Xbox.
While I indeed don't know that much about GForce and as said, almost certainly won't use it...
Sony does allow separate "next gen" versions and separate "next gen" dlcs to existing "last gen " games.
They can't really stop them without alienating many developers who do just that!
While I can't really see a reason they would want to stop them - yes indeed, they don't allow developers release separate versions of games for base PS4 Vs PS4 Pro or to only release PS4 Pro exclusive games (beyond allowing the Pro run higher resolution or frame rate versions of the same games, as they already intended), because PS4 is supposed to all be one platform


...
But the PS5 is different to the PS4 and a native version of Elite on PS5 would be a different game to the PS4 version and whether it would have any connection to the PS4 version beyond an initial transfer, would be 100% Frontier's choice (however unlikely shared progress between two such versions would be now, or even before today's announcement!)
For example, Cyberpunk 2077 is getting a "next gen" only expansion in the form of Phantom Liberty, while Final Fantasy 15 got some "next gen" only content, to name just two games...
IF Frontier made "next gen" versions of Elite with or without Odyssey, I'm sure Sony'd be all too happy for it to exist for people to buy and keep playing on their systems!
