@GameDadGrantNo, but in the ideal scenario Nintendo is at least localizing Mother 3.
Kururin and Rhythm Tengoku don't really require reading.
On the DS side, again Ouendan can be played feeling your way through menus.
GC CX 2 and SaGa are the most unlikely releases and the most text-heavy, but a guy can dream. Probably you can get through Game Center with a FAQ? And I've played the original SaGa games on Game Boy so much, I don't think I need the text.
