Latest attempt at viral marketing shows a pastoral view, faint midi music, and the number "4"--leading some to link page to "4 Warriors of Light" trademark. A large number "4" is displayed prominently in the meadow to the right, under the timer. By turning up the volume, a faint majestic-sounding MIDI-tune can also be heard. While the theme is unfamiliar, there are hints as to what the game might be. According to the Industrial Property Digital Library--Japan's answer to the US Patent and Trademark Office--Square Enix trademarked the title "Hikari no 4 Senshi" (4 Warriors of Light) this past April. In its description, items ranging from video game software to mobile phone straps and collectible trading cards could be covered by the trademark. One theory is that the aforementioned "4 Warriors of Light" could be related to the original band of heroes in the first Final Fantasy, which was released in 1987 on the Nintendo Entertainment System (NES). Since then, the Final Fantasy series has gone on to sell more than 85 million units worldwide on a host of platforms. Most recently, the PlayStation Network reissue of Final Fantasy VII sold 100,000 copies in two weeks just this past month.
