Kwaad... This is just the highest possible number Nintendo could come up with... They're counting everything... Probably including localizations... Its just supposed to sound impressive, not be taken seriously...
Just because... Here is a list of upcoming Nintendo-published Wii games...
Forever Blue
Pokemon Revolution
Kirby
Mario Party 8
Fire Emblem
Battalion Wars 2
Disaster
Mario Strikers
Big Brain Academy
Animal Crossing
Wii Health Pack
Wii Music
Super Mario Galaxy
HAMMER
DK Bongo
Metroid Prime
Smash Bros.
That's just announced titles. We've also heard talk of new Zelda, Donkey Kong, Kid Icarus... And Nintendo often works by letting small teams spend a year or so developing unique gameplay mechanisms... Then they take the good ones, put whoever's team invented them in charge of a project with a more substantial workforce... And then Miyamoto sticks his nose in a year into development and tells them what to fix... They delay the game 6 months, and then it debuts to rave reviews... That's how Nintendo works... But for this giant number, they're probably counting half a dozen small teams that are just being given free rein to come up with new concepts...
And btw, I'm wondering which of the cheap games Nintendo has made have they sold for 50 bucks? Wii Sports is a pack-in, Wii Play is $10 + controller, Brain Age is $20... And casual games like Animal Crossing and Nintendogs probably have normal, longer development cycles. In fact Nintendo has made a point with DS to allow a wide variety of price points (the caveat being that they rarely cut prices). I expect that Wii-branded titles will largely be $30 or $40.
Edit: Oh, I remember. You felt ripped off by WarioWare... I'm not sure if you know, but about half of Wario comes AFTER the credits roll. There's a whole bunch of other stuff to unlock, of varying fun-ness. The best being Pyoro Z (something like that...) I don't feel too bad for you though, because the reviews mostly said it was a depthless game good for a casual party atmosphere.

"The way to solve this problem lies in how to communicate what kind of games [they CAN play]."
