While I understand a lot of players would love to see the big map update that went stable on PC fairly recently, I must refer to the Console Version FAQ
So while we don’t know a timeline or confirmation of those features being ported, we know the team want to try port what they can. Porting any item or feature to console takes time, some items take longer than others. But as always any new information will be posted in News and Announcements once it is available.
Similarly the Island creation is limited but we may hopefully see that change in the future. The limits on placing items in the map creation are there at the moment to prevent islands from being overloaded which could cause issues.
