Guitar Hero 5 on Wii is $60?!?

[wiifan75]

I remember something when Wii released that Nintendo had a pricing system in place for every one to abide by.  No games over $50 and sub par games would be no more than $40.  Am I crazy to remember this or was it true?  I can't believe Guitar Hero 5 selling for the same price as PS360 versions and the PS2 version is under $40.  I've never agreed with any games costing over $50 and I want this game but I'm content to wait until the price drops to $49.99 or less.  I'm voting with my dollars to keep games priced at $50 or less new.  What the consensus in here?  Am I really going crazy with this?
