I fondly remember a similar deal with Xbox360 games on launch day. Here's hoping some PS3 titles get some luv @ Target eventually.
In any case, here's the tentative list of launch day Wii titles (according to
http://en.wikipedia.org/wiki/Wii#Confirmed_launch_titles ) :
Avatar: The Last Airbender (THQ Studio)
Barnyard (THQ)
Blazing Angels: Squadrons of WWII (Ubisoft)
Call of Duty 3 (Activision)
