I honestly don't know why people are expecting some great planetary landing game, or even ship/station exploration.
My philosophy on this subject at the moment is this: I'll believe it when I see it. FD has given no indication that they will be able to pull off a meaningful planetary exploration or individual exploration game. What we'll likely get is maybe a few ad hoc attempts to do it that amount to very little in the end. Honestly, who thinks we're going to be able to land on planets and explore the entire planet? I hope no one. It will likely be some random small zoned thingy which you can do very little, that happens to look "somewhat" like the planet from space. This is assuming we see anything like this at all.
If you want planetary landing's, best to look towards No Man's Sky, who included the prospect as a cornerstone of the game's functions. It's going to be quite difficult for FD to shoehorn such huge features into the game at this point. Furthermore, given their track record with ED so far, even if such features were implemented, expect a plethora of issues and bugs. FD should just focus on adding walking around in ships and fixing what's there, and adding more variety/missions to the space game (c'mon, not a single escort mission?).
