If this really was the case, good on Valve for sticking to their guns. Ubisoft sucks donkey balls when it comes to regional pricing (much like EA).
Assassin's Creed Unity Standard (for some reason they've named it "Special Edition" probably for pre-order tantalization purposes) costs 60 Euros (~$75 USD). It costs $60 USD everywhere else.
They can't seem to grasp the concept that 1 Euro ≠ $1 USD. Then they complain about how PC titles aren't selling very well.
