I wish they could provide any information about that update instead of being completely silent.
from my experiences i can guess that there are a few problems with this
the entire premise is very simple and the only thing to show is the end goal. if the end goal is not achieved, you essentially have a diary of failures and experimentation with nothing really meaningful to the average user
they're making some changes to the game and it's all too technical to show some pretty pictures until the technical stuff is worked out
also the fact that people get really anxious when they see something pretty and don't get it until way into the future. also, what happens if the undertaking proves too ambitious? gota consider it from the point of view of a game developer and not the player
