The primary reason we haven't seen a major shift yet (and won't see one for awhile) is simply development times ...
Many of the highest quality games of the previous generation took 18 to 24 months to develop and (I expect) many of the highest quality PS3/XBox 360 games probably are in the 24 to 30 month of development range; this means that (in the worst case scenerio) it could be 54 months from when the Wii launched before we saw a game released from certain developers.
On average, I would expect that you would start seeing development resources that were shifted from PS3/XBox 360 development release games 24 to 48 months after the Wii had released (assuming that the Wii was still popular when the game begins development).
