Are ship interiors confirmed? I haven't seen anything specific about that.
I'm just imagineering - like all the other random speculation on the web based on a single, short video.
Personally I'm past caring.
I bought Elite because I thought it was an intelligent game. But as it's developed the imaginative and intelligent bits seem to have been pushed into the background. There seems to be no plot any more. The reward system is unbalanced beyond belief, the much vaunted fleet carriers turned out to be a spaceport with a FSD, rather than just a base for your own ships, and at a price 96% of us can't afford.
The pointless obsession with mining, so you can earn lots of credits, to buy a FC, so you do more mining to pay for the upkeep etc etc is plain mad.
Things that could have been developed for the benefit of all have been ignored. The missions are the same boring stuff reworded and full of the usual brain dead stuff about assassination and massacres. The crappy HUD is unchanged, there's no on-screen menus outside of the clunky panels, The NPCs are ignorable, the spaceports are basically all the same models, the SRV looks like it was designed in the 1960's.
I could go on until it gets dark - but there's no point.
IMHO the game is broken. Frontier have paid too much attention to the verbose top 5% who play with the sole intention of slaughtering everything in sight and ignored the rest of us who hoped for something different to yet another sad shoot-em-up.
Personally I have little hope for the future. The short video showing space-legs didn't look that impressive. Rather depressing to notice that the first thing that caught the attention was the weapons !!
I can't see what tenuous atmosphere's will add to the game. The sky won't be black - but that's it. You're unlikely to burn up on entry - all that happens normally is that the ship effectively stops when you get it wrong. Space legs will probably mean you'll just be able to do even more mining and kill more things from a different perspective.
Unless Odyssey goes off on a completely new tangent with, as yet undisclosed, new content the game is dead.
PS:
I suspect Frontier don't care much either - they just want everybody to buy Planet Zoo.
