According to a piece from the Asahi Shimbun Nippon, Paper Mario 3DS is going to be advertised and released in Japan, this Fall.  If this statement is true, then obviously the 3DS itself would have to be released this year as well, right?  We'll find out for sure on September 29th.  And as I stated before, my personal belief is that the system will come out on Sunday, November 21st in the United States for $249.99 and be packed in with a game.
