Cave is going to release this on Xbox on May 30th, and better yet, they have plans on releasing it out of Japan already! They are hoping for a simultaneous launch in Japan and the West, which I really hope happens! It's great to see developers like Cave getting their games released outside of Japan and trying to get it available to others as soon as they can. I think having both released at the same time would be awesome!
