Further add: This is up to the retailers as of right now, for example here:

Where I buy it, I get it for 54.99.
I remember back when Canadian dollar was even above the USD, some retailers still had the 69.99 for months.
HMV for example still had those prices for awhile, and I bought Infinite Undiscovery for that price.... my worst purchase in my life. Not only was it 10 dollar cheaper at other places, but it was the worst game I ever placed.
