According to a Nintendo Spain press release, they may be bringing Monster Hunter 4 to the Salon del Manga XIX event happening in Barcelona on October 31st.
This is big news, as there has been no announcements about any Western localization of Monster Hunter 4 from Capcom. If this is true, and not just a typo, then that sound you hear is me cheering and jumping up and down.

PERSONAL UPDATE: Something in my gut tells me this isn't actually happening. The biggest clue is that it's a Manga fair, which suggests that they're just bringing the Japanese version to let people try it out.
