Based on monthly average the last time euro was 1.20284 USD (20% VAT) was in march 2006. In december 2007 it was 1.45517 USD (45% VAT???).
I guess they are just slow to take account the currency changes (its not like anyone forces them to do it). Perhaps once per year or two. I know one online shop in america that does it perhaps twice per year and the prices became real low during the last year (20-30€ for new games). Made me buy more than few of their games.
