Not only that but, 10 other titles were discovered. The thing to note about those 8 is that they're Wii titles. We don't know all of them, so I guessed on some. Here they are:
Guitar Hero III: Legends of Rock?
NBA Live 208?
Japanese puzzle game
Also a Japanese puzzle game
What does it mean? Who knows. Maybe nothing.
