OK, so here's a list of what I would consider the non-casual games for the GCN from 2002 (which should be comparable to 2007 for the Wii). AC is borderline casual, but I included it here to be conservative.
GameCube Wave Race: Blue Storm
GameCube Super Smash Bros. Melee
GameCube Super Mario Sunshine
GameCube Animal Crossing
GameCube Eternal Darkness: Sanity's Requiem
And here's a list of released and expected non-casual games for the Wii for 2007.
Wii Super Paper Mario
Wii Mario Strikers Charged
Wii Metroid Prime 3: Corruption
Wii Battalion Wars 2
Wii Fire Emblem: Goddess of Dawn
Wii Super Smash Bros. Brawl
Wii Mario & Sonic at the Olympic Games
Wii Super Mario Galaxy
Obviously these list are subjective, but other people could put there own lists together to make an evaluation. By my own evaluation, though, it looks like Nintendo has boosted non-casual game production by over 50%.
