Mods will most likely be able to port over without much issue. Most games that receive console ports don't alter the game structure too much; Thus, as long as authors can make slight changes to conform to whatever standard Microsoft requires, shouldn't be much of an issue. The whole point, I think, behind Xbox receiving the port is due to Sony's harsh mod policy (Tight restrictions on all "external" assets including, models, textures, and ESPECIALLY scripts.) With modding being one the cornerstones of Starbound's re-playability, I doubt their decision to focus on Xbox over Sony was anything less than a calculated decision. I'd be careful, that's a statement very short of insulting mod authors... Personally, I find it a rather subjective point of view. I know there are some styles and work that I find rather unappealing, whereas many other find enthralling.
