Today the European pre-orders started for Windows 7.
(Disclaimer these links go through my Associates account).
Keep in mind these are full versions not upgrades. So it really is a good deal, the only disadvantage is you cannot perform upgrades at all with these, due to Internet Explorer being removed from the European editions. You also get both 32-bit and 64-bit versions in these packages.
Get 'em now while they're still for the offer price.
