The Xbox version will be updated frequently (although not always as quickly as on PC), and will be upgraded for free to Buy ARK Items the full version once that's released - at $34.99, Rapczak also mentioned that it's cheaper to buy now than it will be upon full release. No UK price has yet been announced.
