This is an image on the Cube notion board for the Party Update, I would say this looks like the Java server because the chat is in the lower left. On this image we see clean looking chat and good looking chat roles, sort of like on Tubnet and MCC island, so I think for the party update Cubacraft will have a texture revamp to make it look more modded and cool.
That's all write your thought's down below on what will happen ;)
