There is nothing to indicate that the Xbox version won't have all the same official patch content as on here. But if by 'every' biome you also mean the ones that occupy the most northerly and southerly parts of the world then no. Those definitely won't be in time for the 2nd of Feb when it launches on Xbox and probably not even 2023. However Mistlands is now expected to be in the stable build by somewhere in early 2023.

Since the Early Access launch there have been no world wipes. The devs have cautioned us that they make no promises when it comes to preserving compatibility with our old saves, but it's not the same as saying that their definitely will be wipes either.

The only drawback of playing old saves in newer patches so far, is that you need to travel to a part of the map that has never been previously loaded in order to find most of the new content.
