This video highlights just how far behind Elite is. No one should be surprised though as nothing significant has been developed over the past five years since launch. Nothing.
No it doesn't really. Games like SC, or should I say tech demo's like SC, are exactly that, just demonstrations, they are no closer to having a space game that features atmospheric planets than ED is, in fact they don't even have a game! As far as MSFS the next generation is concerned they don't actually have a planet, the scenery is done from Bing satellite images, isn't actually an interactive environment and even the devs have said once you get to close the illusion starts to break down because the algorithms that convert the flat 2D image into a realistic 3D scene don't work up close.
On the other hand we know nothing regarding what ED has been doing over the last few years as far as atmospheric planets is concerned and that's not really a surprise having seen the behaviour of the ED online community over the last few years. Whether it will be part of the big release in 2020 I have no idea, but if it isn't I will be surprised because that's supposed to be a game changing update and I don't really see anything else in the future that will have that effect.
