A few things noticed in the trailer that some may not notice: the Fashion Melon lowers sanity when worn, the wet meter is still in winter, it seems that she doesn't take any damage while wearing the helmet (she may be taking damage but the bar doesn't drop), the statue she passes looks like a werid spider-bee hybrid (possible bee queen?), the deciduous trees are now called "Birchnut trees," catcoons may need to be escorted to their hollow stumps to spit something out for the player, tumbleweeds still roll out of the desert biome, wet objects now have a thin blue box around them, and the craftable(?) bell item uses 33% durability. Hope this helps with analysing it and the new features.
