Meh. I must be the only person who sees Wii advertisements...
TV Ads: Super Paper Mario, Mario Strikers Charged, Metroid Prime, Galaxy, Phantom Hourglass...
Magazine ads: Fire Emblem + Phantom Hourglass
Online ads: All of the TV ones + Fire Emblem, Battallion Wars 2, Donkey Kong: Jet Blast, Phantom Hourglass.
And I still haven't seen a Bioschok ad(I hear they show up on Spike TV/MTV, but I don't watch either)
Also, Galaxy is being advertised every night for hours on ABC Family(Every Holiday movie is being 'brought to you by Super Mario Galaxy for Wii')
