Additionally, here's the Japan launches for the Wii and DS.
Wii:
Week 1: Twilight Princess, Wii Sports, Warioware, Wii Play
Within half a year: Super Paper Mario, Excite Truck, Brain Academy Wii Degree, Fire Emblem Radiant Dawn
DS:
Week 1: Super Mario 64, Warioware, Pokemon Dash, Band Brothers,
Within half a year: Yoshi Touch & Go, Touch Kirby, Brain Training, Nintendogs
Neither had very strong lineup from scratch at all. The 3DS looks to have something along the lines of
3DS:
Week 1: Nintendogs 2, Professor Layton,
Within half a year: Ocarina of Time, Pilot Wings, Steel Diver, Runabout for Nintendo 3DS, Grand Strategy 3DS
Note that in Japan, Layton is about the same size as portable Zeldas, both just slightly smaller than Super Mario 64 was.
The 3DS definitely has a stronger launch from Nintendo than the DS or Wii did.
