Indeed, various dev posts have ruled out some options (first-person / walking around ships for example) but planetary landings has definitely not been one of them AFAIK.
Well so many folks are saying this so I apologize for muddying the waters.
The way planetary landings has always been advertised has been with the devs idea that there would be awesome things to do when you landed. Which always meant that planetary landings and FPS and Walking around were supposed to happen together. They obviously do not need to..and there was discussion that they would start with the less complicated worlds (rocky and icy) before they moved into earth-likes, water, etc.
I still say the this would be weak sauce, when the term 'colossal' was thrown about. I would be more excited if they announced the Panther Clipper would be the only thing that was in the next update. At least that would be literally 'colossal'.
