Path of Exile expansions expected once a year
Path of Exile will receive expansions for somewhere between five and ten years, Grinding Gears boss Chris Wilson told Joystiq at GDC. The dungeon crawler is still in open beta, but is expected to hit version 1.0 later this year, and will add an extra story act at that time; Wilson said that kind of expansion is "probably a once a year thing".
