Special/significant in the way of working with Nintendo of America to promote the game through their channels, since this is the first Nintendo Miku game to hit western shores.
Could we expect 3ds decals or themes as well, or are the physical pre-order items that we've been shown the limit?
Also, why do you think Project X Zone was so popular in the West but less so in Japan? Was that the main reason for making a sequel and is it possible that the game will be used to draw attention to certain properties to improve their chances of getting sequels/updates, like Axel from Streets of Rage's appearance?
Also, any further characters in PxZ 2 you can give out, or is that pretty much the entire roster now?
