Well, this is an interesting find. Taking a look at the careers section of the European SE website, we found out today that they are hiring for English/French/Italian/German/Spanish Localisation Testers. Originally SE had hinted that a Spanish language version of the game may be possible if their was enough demand for it. Now it appears that this is a concrete reality.

This Spanish localization would really help U.S. fans like me who want a fun and exciting way to brush up our Spanish language skills. If this pans out, just remember to mind the differences in dialects and cultures among different countries when choosing a linkshell.
