I think Graces will bring the most immediate boost, but it's going to be obscured by the holidays. Musou 3/NSMB week should be decent, but as big as some expect imo.
Relying on single games to boost sales is a losing strategy though, what you need is a full, deep schedule with variety to keep sales going (see: PS2, DS). Wii has that for the holidays at least (in Japan).
