It's no secret that Professor Layton and the Mask of Miracle will eventually be released worldwide. It was a 3DS launch title in Japan, and although we always have to be patient, the puzzle-master with the wonderful hat always makes his way to the West. According to recent reports, that arrival may not be far away.
According to Siliconera, Nintendo has recently filed a trademark for Professor Layton and the Miracle Mask in the U.S., which could be the title for the North American release. This isn't the first time that a trademark has appeared just before E3, with the Professor's last two DS titles appearing in this way just prior to a reveal at the LA extravaganza.
Nintendo Europe previously confirmed Professor Layton for 3DS in 2012. It's possible that the PAL release will have a different title to North America, but at the very least it looks like the waiting may be almost over.
