Give them time. Yes, the Cube damaged Nintendo's credibility but the Wii is bringing back their good name.
Take Harvey Norman for example. I remember seeing all the gamecube games in the clearance bin and asking if they were going to still going to stock cube games, I pretty much got laughed at.
Years later, I asked if they were doing a pre-order deal for the Wii, they laughed, this time a little harder.
Then a couple of months after the Wii's release I went there and low and behold they had Wii products in stock. This time I was the one laughing!
