Well, here in Portugal those kind of timed promotions by Microsoft are common, given that it's way behind the Wii and PS3 in terms of sales.
Game and Fnac usually have timed drops of 50€ or so when it comes close to the holiday season, plus there's tons of deals from other stores such as Vobis, Jumbo Box and so on at varied intervals.
So this is actually not news worthy, at least not for Portugal.
