Heheh so far my OP pretty much nails it
I'm really excited to see all this in action. The issue of what happens to your ship once you leave it will surely be a hot one ; I just hope you can't go back to your landing location to see your ship was blown up and you're stranded on the planet, forced to kill yourself to respawn at a station. Once landed and without anyone inside, a ship should be like a piece of scenery, simply invulnerable. Otherwise people will simply be too scared to leave their ships.
I'm also interested in seeing that "obrital cruise" mechanic they talked about during the stream today, and how it will allow us to approach planets. Will we have a transition screen like the FSD shutdown when we approach a station? If so, at what point will it happen?
Another thing I'm wondering about, is wether we will need to approach a planet (or land on it) before we know if there is something interesting on it, or if points of interest will pop up as we fly by the planet in supercruise... Also, I hope the frequency at which we encounter wreckages or pirate bases will be reasonable, it won't be very believable if there are dozens of shipwrecks on every rock. But I'm confident the procedural generation will be well made in regards to this.
Finally, I hope we will have planetside outposts on some moons, basically like the ones in space except the landing platform will be on firm ground.
