Here's a list of titles for the Wii that should be available in at least one of the major markets in time for this Holiday shopping season (some are JP only for this year, to be released next year in NA/EU). I merely picked the titles that hold some interest for me so if I left something off that you are looking forward to or made a mistake then that's either an oversight or just due to my bad taste...
Battalion Wars 2
Guitar Hero 3
Dance Dance Revolution, Hottest Party
Final Fantasy, Crystal Bearers
Fire Emblem, Goddess of Dawn
Soul Calibur Legends
Kings Story
No More Heroes
Tales of Symphonia 2
Chocobo Mystery Dunegon
Animal Crossing
Harvest Moon
My Sims
Dewys Adventure
Nights, Journey of Dreams
Zack n' Wiki
Manhunt 2
Red Steel 2
Disaster, Day of Crisis
Bully, Scholarship Edition
Trauma Center, New Blood
Endless Ocean
Geometry Wars Galaxy
Super Paper Mario
Mario Kart
Super Smash Brothers Brawl
Metroid Prime 3
WiiMusic
WiiFit
Super Mario Galaxy
Sword of Legendia
This lineup looks very powerful to me. After cogitating on it awhile I was struck by how similar it is starting to look compared to the DS libary. I really think the mojo guiding the DS has been tapped into by the Wii. That is good for the future of the Wii if it pans out that way. It appears to me that a critical mass of titles will soon be available. Out of the thirty titles listed my low end estimate is that 10 of them will get 8+ ratings. Again, low end estimate, 4 of them will get 9+ ratings. If that happens then there will be enough entertainment on the Wii for me until we see Dec '08 roll around. Of course there will probably be some great titles released throughout '08 so I suspect Wii will be busy.
