Night of the Sacrifice
Pokemon Wii game
The Last Story (likely come to the west)
Earth Seeker (from the guy(s) who maxe Monster Hunter games)
Xenoblade (likely to come to the west)
Pikmin 3 (Miyamoto has near confirmed it)
Rhythm Heaven Wii
Rodea Sky Soldeir (a game by Sonic creator Yuji Naka)
Conduit 2
The Grinder (Wii version is different than others)
Fatal Frame 5 (hopefully will come to the west)
