Looks like fans of Sega's Shenmue will have to pick up an Xbox for more Shenmue games, as Microsoft and Sega have announced a new deal which will see Shenmue sequels appearing exclusively on the Xbox in the U.S market, with new Phantasy Star Online games appearing on the Xbox as well, though not exclusively. Sega and MS will also work together to create a motherboard for arcade machines based on Xbox technology.
