community actually voted or pushed on it not to change until we get like a major tech implemented or had a big addition besides planets like the gas giant were getting in a few days. So that's mostly on the backers. Im surprised since they have gotten one of the big techs before server meshing done and it hasnt changed. i guess people just forgot about it.
Clouds are done, at least the first iteration and its going to be in the game for us in about a week or 2. Culling i belive they will hit, door alignment is mostly like a small technical addition for the doors to dynamically go down depending on how the players landed and how far down the ground is. Something small but will be helpful.
The million players thing is still being worked on and they have said their aiming for this year, they go into more detail on monthly reports. That counts as one of the more major techs like the Icache system which also wasnt on the roadmap but is on the progress tracker. ITs competed already. They get a decent amount of stuff done and info out about things once in a blue moon your going to miss large swaths of info.
